If you feel that the input level on the Analog Heat MKI/MKII is lower than expected, there is a technical reason for why it is like this. Then input level on the Analog Heat is set like it is by design.

The Analog Heat attenuates (lowers) the incoming signal to create headroom for the distortion circuits and the filter. If it didn't do that, the levels would be too high and cause internal clipping if you use heavy distortion and turn up the resonance on the filter.

You can always use the LEVEL parameter to gain the level back up if you feel that the volume is to low after passing through the distortion, filter, and EQ.

This information applies to Analog Four, Analog Keys, Analog Four MKII, Analog Heat, Analog Heat MKII, Analog Heat +FX, Analog Rytm, Analog Rytm MKII, Digitakt, Digitakt II, Digitone, Digitone Keys, Digitone II, Syntakt, Model:Cycles, and Model: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.

TROUBLESHOOTING YOUR ELEKTRON DEVICE

If you are experiencing problems with your Elektron device, there are several different things you should do before you contact Elektron support. There are a couple of ways to self diagnose your device. Please use this guide to determine whether the problem is hardware related or in the software/firmware.

A. Basic troubleshooting

To make sure that the issue isn’t software related, and/or caused by external interference (such as incoming MIDI data causing MIDI feedback), please do the following, and then check if the problem is still there after each step of it is solved: 

1. Install the latest OS for your Elektron device. Available for download here.

2. Unplug all MIDI cables and the USB cable from the device.

3. Perform a factory reset. Read more about factory reset here.

4. Create a new project.

B. TEST mode (not available on Model:Samples, Model:Cycles, and Analog Drive)

In TEST mode, you can perform a variety of tasks to determine the health status of your device. If you have any trouble with your device and suspect it may be due to a hardware problem, perform this self-test.

1. Hold down the [FUNC] button on ([ACTIVE]/[ON] for Analog Heat) your device while powering it up to enter the STARTUP menu.

2. In the STARTUP menu, press the appropriate button to enter the TEST mode.
   WARNING: For testing purposes on some Elektron devices, a short, loud beep is heard through all outputs of the unit when you enter the TEST mode. If you encounter any errors here, it might be a sign that there is a problem with the device.

3. In this mode, it is also possible to check the buttons and encoders/potentiometers functionality. Depending on which device you are using, most buttons either light up a led-light and the display shows which button is pressed, or turn the display on/off. This method is an excellent way to confirm if a button is broken or not. If the device doesn’t register a button press, then it’s likely that the button needs to be replaced. (MASTER VOLUME does not give any indication on the screen when it is turned). Various sequencer button combinations change the color on the button mechanisms on the devices where this is available.

If the information above did not solve the problems, please proceed to this article.

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.
