does this happen to you?

When I change patches on Rhino, if the previous note is still fading I get a really obnoxious BRRRAPT sound for a second or so, before the new patch is initialized. This happens both in Ableton and using Savihost (ASIO) using a Presonus Firebox interface.

If this is a Rhino problem I hope Tick will read this and try to zero the output or something before the patch change occurs.

If this is just my interface being wonky then, still any suggestions? It makes patch auditioning very unpleasant.

PS much love for Rhino, still my favorite synth.

Blackflag,

When you change presets, an incredible number of things happen: envelopes and modulation curves are precomputed, oscillator waveforms are loaded from disk and unpacked, sometimes computed through the additive engine, ...
Because of this, cpu spikes can occur. These spikes are responsible for the noise you're hearing. The output is actually zeroed out, but your cpu is overloading for a fraction of second, hence the noise.

Hi Tick,

That makes sense. However theres another strange aspect to it, which is that patch changes take much longer (and hence much more aggravating) when there's still audio trailing off. In other words if I change from patch A to B with no audio happening, it might take 1/4 sec. But if I release my note and then immediately do a patch change while audio still tapers off, it buzzes mercilessly and might take 1 - 1.5 sec.

Again I'm not necessarily putting this on you, it might be something else in my setup that cant handle audio stuck in the buffer while the CPU is loaded. But might as well make you aware in case it makes you say "aha" or something.

Otherwise I'll just count to 5 between patch changes.

or use 2 instance of Rhino...

Yeah the problem happens more when I am paging through patches for previewing. I dont usually use patch changes in the middle of a track anyway.
