Hi, as a premise, I'm a very beginner with SE, I just downloaded the demo (I will decide whether to register) just because for some research purposes I needed to experiment with some audio processing ideas which unfortunately no VST around (AFAIK) allows me to do... so I have to write mine... or at least I'm trying...
I am pretty trying to implement a simple audio processing FX where a delay time on the incoming signal is modulated by the MIDI note (for example, doing that on a white noise can generate interesting sounds).
The big obstacle I'm facing is that the pitch voltage coming out the MIDI TO CV is linear of course (well... apparently it is 1 V / octave with an offset I have still to figure out - a voltmeter connected there sumply goes nuts even within a container and with MIDI TO CV set to MONO), but to properly control the delay time (in ms) this value has to be properly offsetted and then converted to an exponential value, in order for the sound produced by the delay to be musically consistent.
I could not find any conversion tool within the builtin modules. The only one which could apparently do an useful job was the Float function but it has serious drawbacks: first of all, it needs the voltage signal to be converted to float first of all (and then perhaps back to voltage), but the conversion operator only works at few Hz. So I suspect this is definitely not the way to go.
Any suggestions ? How can I properly convert the pitch signal to a suitable exponential (after offsetting if needed, of course) ?
Thanks
