Ah Yeh its not called wave table index in the MIDI CC appendix as that terminology is only specific to wave table OSC types, and as you know you can choose from MANY osc types…so its called waveshape/index or something.
So it depends on what osc type you have selected in the patch, automating this cc will have an effect on any osc type you choose, just a different type of outcome for each osc type… But all do something interesting…So if you have the osc type set to any of the wavetable osc types then it will index through the wave table, if you have it set to the classic subtractive osc it will blend between the two waves you have selected in the oscillator, if you are set to hypersaw it will controll the density of the hyper saw (1 to 9 but very smoothly)…
CC 17 for OSC 1
CC 22 for OCS 2
Here are my other favorite things to mod with triggerless p locks of a DT LFO switching rate in tempo…
Ring MOD volume CC 38
FM amount osc 2 CC 27
OSC 1 Pulse Width CC 18 (on certain waves not sine hahaha)
OSC 2 Pulse Width CC 23 (on certain waves not sine hahaha)
OSC Main Volume CC 36 (goes into saturation from 100 to 127!!! so if you set the saturation curve in the filter section as a wave shaper or bit crusher you blend between gnarly and gnarlier in a very rhythmic Elektron way)… going into and out of saturation or digital distortion in a fraction division of the bpm.
Saying all that dont forget the virus has a complex matrix and 3 LFOs as part of its architecture, Which are very controllable and have access to more parameters than the direct MIDI in limits…So… you can also set A Digitakt send CC of 87 (virus LFO 2 to FM amount) and a second Digitakt send of CC79 (Virus LFO 2 Rate) and let the DT control the internal LFOs of the Virus…you could seta 3rd Digitakt CC52 to switch up the shape of the LFO rhythmically or switch filter types LP HP etc…using this method you can control the filters with the Virus internal LFO2…the amounts can be accessed through CC88 and CC89 and the LFO Rate again is controllable through CC79…etc etc etc Letting the Virus do the work internally and maybe solving any of the above mentioned MIDI overflow as the data sent is a far less continuous stream…! the above parameters are always the same in each patch so its a great start point for a Digitakt Template.
And if you havn’t had enough of me and want to get your hands real dirty… you could set a matrix slot in an individual Virus patch to control ANYTHING!! Set a Matrix Slot for Virus LFO 1 and let it control -:
Filter bank frequency - set to Vowel Filter Set with Hi Resonance (oooohhhhawwww)
Distortion Intensity - distortion set to Bit Reducer (Robot oooohhhawwww)
Phaser amount - (70s space robot oooohhhawww)
Then control the Virus LFO 1 the same way as above letting the virus do the LFO and the DT Plocking the changes with the beat.
Thats just one of six slots available!! have fun…!
