reaktor pitch mod question

hi,

i'm new to reaktor.

ive been made a bassdrum generator placed as vsti (ableton live 8). based on sine oscillator and pitch modulation (adsr) + some filter. pretty simple.
the problem is highest control rate is only 33khz and the adsr causes inaccurate pitch modulation. at the end every kickdrum sounds a bit different especially on the beginning of the kickdrum which is the "click" part. when i lower the control rate it worsen. how can i avoid this?

i suspect there is a way to use the audio rate as control (wich in my case is 44100 not 33k and maybe this is the cause of the imperfection?)

 

Reaktor has a range of FM oscillators, with FM inputs that accept audio rate inputs, so that might be a place to start.

These inputs are linear though (you're modulating linear FM rather than logarithmic pitch, where for every 12 units the frequency of the oscillator is multiplied by 2). So an envelope modulating frequency won't sound the same as an envelope modulating pitch, even if it results in the same amount of frequency sweep.

But you could put the output of your ADSR through a power function or a logarithm function to compensate and give yourself the kind of frequency curve you're looking for? Here's a quick ensemble (there are a few notes attached to the controls), and it uses a tuneable power function to change how the FM envelope behaves. I'm on a laptop with crappy speakers so I'm not getting a lot of bass... hope it's useful.

 

thanks m3m for the quick reply!

actually you were too quick.
your example gives the same results. every one sounds a bit different.
for now i've found a solution.
using A/E (perm) instead if a simple A/E for the adsr then i feed the a/e perm with the system panesl audio rate then the control rate is exactly as the audio.
now its perfect!

thanks anyway.
r5 has a better learning curve as i thought but im pretty sure i will be back soon with other questions

cheers,
peter

 

i only understand it half but maybe the sync sine oscillator works
