Hey atrickp, I’m not sure if I got your question right, but I hope, this description will help you.
This patch uses 8 loopers at a time, so you will need to be able to switch between 8 banks, sending midi data on channel 1 to 8 respectively. I use a Behringer BCF2000, but I think the Korg Nano Kontrol is similar. Please note, that all global messages like main volume of each looper are sent on midi channel 16. This might seem complicated, but is because I also use a Novation Nocturn controller to have the most important functions like main volume or monitor volume of each looper directly accessible.
I will now describe the settings (the way I use it) for channel 1, the other 7 are analog to that.
Bank 1: fader 1 would be the volume for looper one, midi channel 16 CC 17 range 0-127.
Fader 2 center position of the sample for looper one, channel 1 CC 10 range 0-127.
Fader 3 playback speed, channel 1 CC 11 range 0-127.
(You can get all details from the midi CC list I sent you, it would be too long to write everything here, so I will just explain how my controller is set up.)
Fader 4 would be playback range, fader 5 volume delay, fader 6 feedback delay, fader 7 sample and hold frequency, fader 8 sample and hold volume (channel 16 CC 26).
With the 8 encoders it would be encoder 1 for panning left-right, encoder 2 windowing value, encoder 3 windowing fade in, encoder 4 windowing fade out, encoder 5 delay time, encoder 6 eq frequency, encoder 7 eq resonance (q), encoder 8 eq gain.
Button 1 start/stop recording, button 2 activate/deactivate reverb, button 3 activate/deactivate eq.
So you have to set up about 20 messages for 8 channels to make everything work. It took me hours to do that on my controller, but for me it was worth the pain. I’m currently working on a preset file for the BCF2000. If you want to, you can add more banks to have for example one bank with all 8 main volumes on the 8 faders or to have a separated monitor volume for each channel, if you want to listen to a certain looper via headphones (monitor out would be output 13 and 14 on your sound card unless you change it at the bottom of the patch).
I hope, my short manual helped you set up the patch and feel free to ask, if you have any more questions. All the best, Chris
