A matrix mixer allows inputs to be mixed to multiple outputs. In the case of this plugin each input ( 1 - 4 ) is stereo, and also each output ( A - D).
we then connect each input ( 1 - 4 ) to each output ( A - D ) using a VCA, which can be set either from the UI ( statically ) or via CV
the mixing can be consider like a bipolar vca or attenuverter, so can also be used to invert signals (with negative vca)
notes:
- the 'level' is per input/output pair e.g. 2D, 3B
- all mixing is done at audio rate
- the parameter vca value is added to any incoming vca cv
this will set a non-zero value to zero (i.e. clear it) , or a zero/clear value to 1.0
the matrix mixer can be for audio or cv mixing, mixing cvs can open up a whole new world of modulation shapes.
you can use either bipolar cv (e.g. LFO) or unipolar (ENV) for the vca input. BUT should should remember a negative value will invert the wave form (which can be fun)
IF you do not want this and prefer it going to zero you have two choices a) use the Percussa's excellent scale and offset controls e.g. scale by 0.5 and offset by +1.0 b) use the VCA level on the UI and set to 1.0 ... this will make it go from 0.0 to 2.0 , so it'll be loud unless you scale it ;)
whilst the mixer is stereo, you can use if for mono signal, the mixer is optimised to only calculate for the input and outputs connected.
also there is not 'connection' between left and right channels, the limitation is they use the same vcas.
whilst panning is not implemented, if you chain two mmx4 this is easy to achieve, with 2 mmx, connected something like:
1L->1L cv=pan -> 1L vca1 -> 1L 2L->1R cv=pan -> 2L vca1 -> 2R 1R->2L cv=-ve pan -> 1R vca2 -> 1R 2R->2R cv=-ve pan -> 2R vca2 -> 2R
