Synth Parameter Testing
I made a Google Sheet of conversions from 0-50 values to the actual meaning (in units like dB, Hz, ms, etc.) of some of the synth parameters. I measured these values by simply dialing in the parameter values (using the select knob to get the exact value, with automation recording), recording the audio on the Deluge, then loading the resulting .WAV file in Audacity and analyzing it there, so they are definitely imprecise and some might be flat out wrong. But it did take hours and hours to make and is probably better than nothing (definitely if you want to program any of the patches from Welsh's Synthesizer Cookbook, something like this is not optional), so here it is: Deluge Synth Parameter Testing
Anyone can comment on the sheet (you probably need to have a Google account). Please feel free to do so if you have anything to add or notice anything I could have done better. (The sheet is a WIP and some parts are a bit of a mess; if you just want to USE it, you should probably ignore the sheets other than "Cheat sheet".)
Edited to add: I also have a tab that just lists the parameters, which was initially a copy of the excellent Deluge Synth Parameter List but I've now extended to include information on which parameters can be modulated / automated / learned (to gold knobs, though I assume MIDI is the same).
