Sounds are stored presets from a track, for example, if you have a specific sound on one of the tracks you can save that setting, which can later be recalled onto any track in any pattern from any project. This includes information about which sample is assigned, the filter settings, LFO modulation, etc. Every parameter on the track will be stored as part of a Sound. The Sound does not store the actual Sample, it only references which Sample has been used. If you delete the Sample from the device, the Sound will no longer be able to load it.

Refer to the product manual for more information about how to use Sounds and Samples.

If you have problems getting your Elektron device connected to Overbridge Engine, there are several ways to solve this depending on what kind of connection problem you have.

MY ELEKTRON DEVICE IS NOT VISIBLE IN OVERBRIDGE ENGINE

Your Elektron device is not visible/not detected in the Overbridge Engine application.

1. Download and install the latest version of Overbridge and device OS. For more information, please see this article about how to install Overbridge.

2. Set your Elektron device to Overbridge mode. For more information, please see the User Manual for your Elektron device.

3. Make sure the USB cable is connected correctly.

If you are using a Mac, please read this article before continuing any further troubleshooting.

MY ELEKTRON DEVICE IS VISIBLE IN OVERBRIDGE ENGINE BUT IS NOT CONNECTING

Overbridge uses local ports to communicate between different applications within the Overbridge suite, and between Overbridge and the computer. But other applications installed on your system may already use the same ports that Overbridge needs for communication. For Overbridge to work, you must close the other applications that use these ports.

Port 46000 needs to be free for Overbridge Engine to be able to communicate with your computer. Also, each Elektron device that you use in Overbridge must be able to use port 460n0, 460n1, and 460n2, where n is the device that you have added.

Example:
If you have two Elektron devices connected, you need to make sure that the following ports are free:

46000 (for Overbridge Engine - Computer communication)
46010, 46011, 46012 (for Elektron device 1 - Overbridge Engine communication)
46020, 46021, 46022 (for Elektron device 2 - Overbridge Engine communication)

Please see this article for information about how to find what ports are in use by the computer's processes and applications, and how to free them up.

MY ELEKTRON DEVICE IS VISIBLE IN OVERBRIDGE ENGINE BUT SHOWS AN ERROR

Your Elektron device is shown as “Measuring” or “Fault” in Overbridge Engine when you try to connect them to Overbridge and it never gets out of this state.

1. Make sure you update to the latest OS for your Elektron device. Available for download here.

2. Configure the devices’ audio channels to send to and from the device in the Overbridge Control Panel. (Only applicable for Analog Rytm MK I, Analog Four MK I, Analog Heat MK I, and Analog Keys.)

3. Another cause of this problem might be because of USB2/USB3 and chipset issues. Please see this article concerning USB2/USB3 and chipset issues and how to solve them.

THE ANALOG FOUR MKI/MKII, AND ANALOG KEYS ENVELOPES

The amplitude envelopes and the assignable envelopes offer 12 different shapes, consisting of six basic shapes each with two different trigging behaviors. The envelope shape graphics indicates how the envelope will affect the modulation destination. The left portion of the graphics shows how the envelope behaves when it is rising, i.e. the attack phase, and to the right the falling behavior is shown, i.e. decay and release. The rise and fall can each be either linear or exponential, useful in different applications as described below. A dot to the left of the visual representation of the envelope indicates that the envelope will restart from level zero each time it is trigged. Envelope shapes without a dot mean the envelope will start from the level it had when being trigged.

0–1 Linear attack and decay/release. An envelope shape suitable for controlling the filters if linear attack/decay/release sweeps are desired. When used as an amplitude envelope the decay and release phase appears to drop quicker towards the end, making it most useful for sounds that should fade out without a tail.

2–3 This can be considered the standard envelope shape. Decay and release fall quicker in the beginning of their phase, behaving more snappy and – just like acoustic sounds tend to do – leaving a tail instead of ending abruptly. This envelope shape is useful for creating distinct sounds, for example, kick drums and basses, but also lengthier sounds like pads.

4–5 Exponential attack, linear decay/release. This shape makes the envelope rise quicker and quicker. This envelope is suitable when for example creating sounds appearing to be played in reverse or for sounds requiring a sudden attack.

6–7 Exponential attack, exponential decay/release. Since our hearing perceives loudness exponentially, this shape is primarily useful as an amplitude envelope for very long sounds that are supposed to fade in and fade out at a very constant rate. When used as a filter envelope, very clicky, whip lash-like sounds can also be obtained by using this shape.

8–9 Full attack, linear decay/release. The envelope will immediately rise to the full envelope level and stay there for the whole attack phase. The ATK parameter sets the duration of this attack phase. The envelope shape is useful as amplitude envelope for certain percussive sounds that need a punch at full volume followed by a quick decay, or for other sounds that should contain a full body before being entering the decay phase.

10–11 Full attack, exponential decay/release. The envelope behaves like shape 8-9 mentioned above, but decay and release will fall in a more snappy fashion, ending with a tail. This makes it even more useful for percussive sounds.

This article explains some of the reasons for crackles, dropouts (gaps in playback) or glitches during playback. Hereafter these will be referred to as simply ‘dropouts’. It also tries to explain why a modern computer can have performance problems although it is powerful enough for the task. It explains the problem domain and tries to give some tips on how you can solve the problems.

USB BANDWIDTH

In some cases, your USB bandwidth might be limited, and this could introduce various problems. There are a couple of reasons why those problems may arise.

Sharing USB Host controller (USB 2.0 Full Speed)

Overbridge for Analog Four MKI, Analog Keys, and Analog Rytm MKI uses USB 2.0 Full Speed. This USB specification limits the data transfer rate to max 12 Mbps. Later Elektron products use USB 2.0 High Speed and have a max rate of 480 Mbps. Many laptops use a single USB host controller that controls all ports. It means that if you have multiple devices connected that run with USB 2.0 Full Speed they might be sharing the 12 Mbps maximum bandwidth. It is, however, possible that your computer has multiple USB host controllers. You can try to connect a device to a different port that might also use a different host controller internally. This might increase the possible bandwidth for each device.

USB 2.0 Full Speed also limits the number of audio channels that can stream simultaneously. If you open the Overbridge Control Panel and configure your USB Full Speed device to use fewer channels and/or a lower bit depth, this might improve the Overbridge performance on your system.

USB Hubs

When connecting a USB 2.0 Full Speed device (12 Mbps) to an STT hub (typical for an internal laptop hub), all devices on that hub are limited by 12 Mbps, even devices that are otherwise High Speed or Super Speed. We recommend that you use an MTT hub (such as the Elektron Overhub) whenever you connect a Full Speed device to your system so as not to constraint your other USB devices.

It is especially important to use an MTT hub if you want to use more than one Full Speed device at the time. Connecting two Analog Four MK1 to an STT hub, for example, causes them both to share only 12 Mbps bandwidth. If they instead connect via an MTT hub, they get 12 Mbps each.

SAMPLE BUFFER SIZE & AUDIO LATENCY

The audible latency in your DAW can be described as the delay time from when the source of an audio stream is played until you hear it. The sample buffer size is the number of audio samples that are processed in each audio packet. A larger buffer size introduces a higher audible latency but might solve problems related to real-time performance as the computer gets a longer time slot to process data. A system with less processing power or more other software/hardware needs a larger buffer size. If you experience dropouts you might have to adjust this to your needs.

• Make sure your DAW is configured with an appropriate sample buffer size for your hardware.

• Please also make sure that Overbridge is configured with an appropriate Plugin Buffer Size in the Overbridge Control Panel.

• If you are on a Mac, adjusting the Buffer Safety Margin in the Overbridge Control Panel can also improve the performance of streaming audio.

• If you are using Windows, adjust the performance mode in the Control Panel to match your hardware.

OTHER CPU INTENSIVE APPLICATIONS RUNNING

Do not run other CPU intensive applications at the same time as Overbridge. These might put a high strain on your computer and limit its real-time capabilities.

Examples of these kinds of applications are:

• Web browsers with multiple open tabs.

• Image or video/3D editor programs.

• Games

AUDIO LATENCY AND REAL-TIME REQUIREMENTS 

Real-time applications, such as a DAW, have very different requirements than other software on your computer. The big difference between a DAW and for example, a video editing program is that in a video editing program the editing is mainly done while the video isn’t playing. After the editing is done the result is played. The processing is allowed to take some time and can be interrupted without you knowing that it was. This is not a real-time process.

Another example is a web browser that is allowed to have a response time from click to result of a few hundred or even thousands of milliseconds before it is deemed unusable. The typical case in a DAW, however, is to run a set of plugins and/or recording sessions while also listening to the output of these. The processing of these sources is always time-limited because if something takes a too long time, it is audible, and the harmonic content becomes distorted and unacceptable. This is a real-time process. 

The sound card converts digital samples to analog from the sample buffer at a fixed frequency, decided by the sample rate in your DAW. It always expects there to be a sample in the buffer to convert. If there is no sample available, it tries to convert empty data, resulting in a dropout. 

It is the CPU of your computer that carries out the actual audio sample processing. The CPU is, at the same time, constantly interrupted by other processes or devices in your system. Therefore, it can’t guarantee to deliver at a specific frequency but is instead given a time slot to deliver. This time is decided by the buffer size and sample rate in your DAW. Audio latency is when the CPU fails to deliver a sample to the buffer in time before the sound card needs to read it. 

The CPU itself is capable of delivering in time on all modern high performing computers. However, as mentioned before, the CPU is always interrupted by other processes or devices on the system. This is not a problem per se, but some devices are more prone to lock up the CPU and not giving it enough time to perform the real-time task of audio processing. Other performance heavy software might also cause the same problem. Therefore, make sure you are not running any heavy processing outside of your DAW.

Listed below are some devices that can easily lock up the CPU.

High probability of lock-up

• Video Cards

• Audio Interfaces

Medium probability of lock-up

• Network Interfaces

• USB Controllers 

• Disk Controllers 

Before troubleshooting the devices, make sure you have all of these devices’ latest drivers.

On a Windows PC you can debug your system by disabling devices in the device manager to figure out which device is causing the CPU to lock up. You can use tools such as DPC Latency Checker or LatencyMon to measure the devices’ latency independently from your DAW setup. If you do find problems when you run these tools, we recommend replacing the device or devices that are causing the problems. If you find no problems with either of these tools, there is a possibility that the problem is with your DAW or a plugin used in your project.

COMPUTER HARDWARE RELATED ISSUES

There are som known incompatibility problems with certain hardware:

• Intel Core2Duo processors, or Xeon CPUs from that same generation, are not supported.

• There could be USB 2.0/3.0 compatibility issues. For more information, please see this article.

• Some USB host controller chipsets have worse performance than others. If you use a USB hub, it adds another chipset in the signal chain and could potentially worsen the performance.
