My problem with the 914 is getting my fingers round the knobs as supplied. Would you say that those slightly chunkier knurled ones make that easier as you can grab them with old knarled fingers even though the space between them is smaller?
Good question. The larger knobs on the 914 block off areas I could get to with the smaller knobs to the sides of the knobs. But top and bottom are clear. Same with 911. I need less 'pinch' to turn knobs now. The little knobs don't give you enough fine control over angular sweep because of the smaller knob diameter. It is eurorack, everything is super-tiny. It's like a moog modular micro-machine.
How did you wire the 914 up to play with the feedback possibilities? Out into a CP3 mixer then out of that back in again? Perhaps my efforts so far have been thwarted by the loss of level going through the unit even when all the knobs are at 10.
Remember the CP3A-M can boost signals by using multiple inputs. I 'mult' the 914 output into three CP3M inputs, then run that into the 914 input. Feedback loop includes the 914 - not just feedback the mixer itself. Use white noise to stimulate the resonant filter, 914 knobs over 7-8 will start the feedback. You need two* CP3A-M's - one for the input to the 914, and one to 'mult' up the output. It'll be a bit of a balancing act unmodified, but can be done with a little effort.
*-actually, I just looked at the patch, you can collapse in down to one mixer with the single white noise source. Playing with it, it seems much easier to control than the stock pots. The real test is a side by side, with I'll get to
Another note on feedback - set the shelving filters to zero, they overlap with the bands and disturb the balance. Also, there seems to be some phase error going on, when I do increase the high shelving, it lowers the output hrough most of it's range in feedback. Interesting. More to look at here. Wish I had my old Bruel and Kjear gear :-)
