A lot of people are asking about Eurorack compatibility. Currently the MAT is designed for use with AUDIO SIGNAL levels and offers low noise and high dynamic range.
CV output:
The 8 outputs are already DC-coupled and offer a voltage range of approx. -2.5V to 2.5V, which already enables a kind of CV control (5 octaves). However, this is more of a side effect and not the intended application.
CV input:
The 16 inputs are NOT DC-coupled and are only intended for audio purposes. You would need level converters to supply them with Eurorack audio levels. But they are quite simple and passive.
So I have also planned an additional extension later on to achieve Eurorack compatibility with additional 16 inputs and 16 outputs, with the audio levels holding 8 outputs and 16 inputs in parallel. This will be an additional available board that can then be stacked between the two existing boards to create a sort of sandwich construction with another two rows of connectors. This way it would also be possible to use the MAT as a bridge between Eurorack and standard audio levels with 16 channel audio in, 8 channel audio out, 16 channel eurorack dc-coupled cv in and 16 channel dc-coupled cv out.
However, there is one problem that is not so easy to solve: The voltage outputs need to be calibrated in hardware to precise voltages in order to use them for voltage-controlled oscillators. This is quite difficult to implement. If you’re OK with using the outputs for gates, envelopes and LFOs, or if you can live with some drift or inaccurate voltage, or if you can do the calibration on the daw side, that wouldn’t be a problem. But I suspect you’re expecting perfect value-voltage behavior. So, let me know…
… But let’s start with the audio version first.
