ctrlRec16
Continous control recorder for 16 outputs. 2 inputs for dual recording (x/y), recording starts when either "rec" of "dub" input is high and stops when it goes low. (use a clock-synced latch before the gate input to tempo-sync recording) Before "dub" can be used, a recording has to be made using the "rec" input. Rec can be any length up to the maximum length of the channel's buffer (buffer=size/16) Dub can overwrite the recording at any position while looping at the rec-length. Individual record channel selection ("channel" input), steps-per-record quantizer ("steps" input. Set to a high number to have a smooth output). Also features a more or less "smooth" randomiser for all channels. This continuously adds a smoothed out random bipolar offset to the buffer depending on change and chance controls. If you have a midicontroller that can both send out "touch" information next to the midiCC, connect this to the "rec" input to automatically start recording when you touch the controller and stop when you release it.
