I don't know enough about Audiomulch to say anything with certainty, but I would assume that it includes OSC integration, and you should be able to map OSC directly to the metasurface without the MIDI intermediary.
OSC would've been perfect. unfortunately audiomulch doesn't include OSC protocol. there is a way around it via MAX or Osculator but not directly. I'd try Osculator but i'm pc only. still digging this topic and looking for PC alternatives.
some time ago ross mentioned he palans to implement it but it doesn't seem to be in the immediate plan for now.
anything that communicates via CC is going to have a value range of 0-127.
i'm thinking of a CC 14bit mode that offers values 0-16383. to quote novation remote sl manual:
"MIDI data values are transmitted as a 7-bit binary number, allowing a maximum value range of 0-127. The MIDI Specification allows for two MIDI control messages to be sent together where the data values form an MSB (most significant byte) and LSB (least significant byte) pair, making a 14-bit binary number and allowing a maximum value range of 0-16383. This is useful where fine control over a parameter is required, however the parameter you are controlling must be able to receive 14-bit MIDI values. If you want to send 14-bit values for fine control over a parameter then set DispType to ‘0-16K’. For CC controls, the MIDI Specification only allows for CC numbers 0 to 31 to be used in this way. Two CC messages are sent when the value of a parameter is changed – the first with the MSB value and the second with the LSB value. To enable the receiving device to distinguish between which CC message has the MSB value and which has the LSB value, the LSB value message is sent using a different CC number, calculated by adding 32 to the original CC number. Consequently CC numbers 32 to 63 are used for sending the LSB value in 0-16K (14-bit) mode.
this works with the encoders but doesn't with the touchpad or joystick of the novation remote sl.
when i assign one encoder for X axis and one to Y axis, set them to 14bit i get a very fine control over the metasurface. but then you need two hands to operate it and it's clumsy to do it this way. unfortunately none of the controllers available on the market offers a 14bit resolution pad or joystick. i guess joystick would be a preferable choice.
