Easiest way to "compress" velocity

torsig1967

I want to compress incoming velocity. That is, I want the incoming interval 1-127 to be - let's say - 90-127.

So far I've done this with Note Scaler, Constant Value and then Control Signal Mixer. Is there an easier way?

(Velocity-> Note Scaler and then a constant added with the mixer)

I don't want to use the audio compressor, it uses too much CPU and I have no control over the exact figures.

Good thing too because the audio compressor wouldn't work anyway :¬).

What would work is a wave-shaper or overdrive. Ableton Live has a nice velocity compressor that works like that, you may wat to grab the free demo and have a look at that and see how different curves work.

Also try different curves in thesame patch to different parameters; that's how "real" instruments work and it can result in very playable patches with a little efford.

Oh, wait, this is for the G1! In that case immediately get the overdrive and never look back. The NM overdrive is perfect for this.

OK, overdrive it will be. Seems a lot easier. Thanks.

I would recommend using a X-Fade module and a Constant module. Set the Constant module to +64 and connect it to one of the X-Fade inputs. Connect the velocity signal to the other X-Fade input. As the fader is adjusted more toward the Constant +64 input, the velocity output of the X-Fade will "compress" within the higher range.

You mentioned 'compressing' the velocity but it sounds like you really just want to reduce the range without actually affecting the response curve. The crossfader idea will work well for this, especially if you want to be able to easily adjust it 'live' from a front panel knob, but if you just want to set it & forget it, there is a less DSP costly way to do it:

Connect a Constant module and the Velocity signal to the two inputs of a blue CONTROL mixer. This module uses even less DSP than the crossfader. Press the LIN button to give the knobs a linear response. Set the two mixer knobs so their values add up to a total of 127. The mixer knob for the Constant module sets the minimum velocity value. For example, set the Constant knob to 90 and the velocity signal knob to 37 (90 + 37 = 127).
