Nevermind I got it.
Where N = 0.5
C = (2^14)*((2^N)-1) = 6786.47500...
Cool trick. Sounds good too.

Re: Anyone interested in Pitch Detection?
Nice
It seems to work. The period value seems to scale. 0.002 gives an octave beneath and 0.0005 gives an octave above.
I'll report back in a few days when I've thoroughly tested it. Much appreciation.

Re: Pitch Shifter: crossfade frequency
Dr Alx,
How did you calculate the ramp speed of 6786
It works, but doesn't seem to fit into the equation in the FV-1 application notes.
How did you calculate the ramp speed of 6786
Code: Select all

Re: Anyone interested in Pitch Detection?
Awesome break down. Those are specifically the two parts I'm having the most trouble understanding. The values of 0.001 and 0.49 definitely do not scale musically. Additionally, the higher up on the instrument you go, the more unmusical (non diatonic) it becomes. Would it be possible to set those of...

Anyone interested in Pitch Detection?
After getting some help with compiling in another thread, I've been playing around with DonStavely's Pitch Detection code from the Infinite Hold"thread . The modeling of the Boss analog method is pretty interesting but the VCO part definitely needs some work. It doesn't spit your fundamental ba...

Re: Spring reverb
I tried this out today. Sounds good! It has a touch of 'boing' that some DSP units go overboard to produce.

Re: Errors Compiling donstavely's Pitch Detection Patch
Well thanks for your help guys. I got the patch working by swapping out those HTML values and replacing a bunch of a integers with floats. The behavior of the pitch detection is quite odd. It sounds a little enharmonic, and I notice that the line with 'log -1.0, -0.49' is responsible for the frequen...

Re: Options for Simulation {Newbie Alert}
Thanks for the thought out response. I've played around with Spincad Designer and it's brilliant work. The ability to loop a wave file and adjust the parameters in real-time quite special. So if I'm understanding you correctly; there is no currently no way to just write some ASM code and test it wit...

Options for Simulation {Newbie Alert}
Hey guys, just getting started with this stuff and would like to start testing code snippets. What I'm looking for is a way to take ASM programs, and simulate them on a wave file. Linux compatibility is a big plus. Spincad Designer does this beautifully with real-time pot adjustment, but doesn't sup...
