Minimum Control Surface + only 5 knobs (knob#)
Posted 26 April 2012 - 02:01
The concept is to program the sound in the editor or via the menus but still be able to control 5 parameters for live playing, assigned on diferent parameters depending on the patch. I guess I would had to alter the fw to make the knobs always act at knob mode (as opposed to envelope mode). What do you say?

Since the mode is not stored in the patch and the machine always starts in envelope mode, you're right about altering the FW.
This can't be much work, if you know what to change. To find out may take some time though.

Yes. You can use any portion of the full CS you wish. Also, have a look at the "KNoBs menu" section in the mbSID v2 user manual.
Would it be possible...

"Knob values can not only be changed within the KNB menu, but also with the 5 rotary encoders of the OSC assign layer. In addition, they can be controlled via analog pots connected to J5.A0..A4 "
What kind of pots are optimal for this and how would I wire them? If I do it this way there's no need to switch to "knb mode" i guess, right? (I mean analog pots connected on J5 are always controlling knb#1-5?)
Thanks again for your time, you have been very helpful!

You wire the pots like those in the mb64, but without an AIN module. They have a better feel for life tweaking than encoders, but they have an absolute position.
So when you switch patches, values will jump to the pots current value and you'll have to readjust. With encoders the values will stay as saved in the patch.
For pots, you'll need to edit the setup_*.asm file, but since this is documented in the CS-section of the manual, it will be easier than editing the firmware to start up in knob mode for the encoders.

I looked at the MB64 documentation to see how to wire the pots and could not find a wiring diagram. Also did not see anything in the wiki.
I also searched the forum and could not find anything.

left pin to Ground
middle pin to J5 on core
right pin to +5V
if this goes from max to min when turned clockwise, exchange left and right pin.
