I take that back. I’ve now added a mix parameter, which controls the ratio of dry/wet signal. Set it at ~50% and you can sing harmony with yourself, with the pitch parameter controlling the harmony voice.

Will the pitch and the time-stretching work also with multichannel files in future versions ?
If you mean the time-stretch that is going to be integrated in Podium, then yes. Up to the full 32 channels, with all channels phase-locked.
I also plan to extend both zPEQ and zPitch to be multi-channel capable, but for that I’m waiting for Steinberg to release the VST3 spec.
ZynewaveKeymasterProgress update:
I’ve found some ways to improve the quality of the time-stretch, but to get better quality the latency of zPitch would have to go up. I don’t think the plugin will be useful if the latency approaches 200 milliseconds. The latency is however not a big problem when integrating time-stretch in Podium, so I’ll be able to benefit from the quality improvements then.
ZynewaveKeymasterHi Justin 🙂 ,
Thanks for your suggestion. I must admit I haven’t tried that hard yet. I don’t have access to a fax machine, so I sent them an email (twice) asking if it would be ok if I just snail-mailed the signed agreement to them. No reply, even though my web-stat showed that someone at propellerheads.se headquarters was surfing my site shortly after my email. So I figured they weren’t that enthusiastic about having another host to support. When I find time to look at Rewire, I’ll just mail the agreement to them, and see if they respond to that.

ZynewaveKeymasterHi,
It is free, but it is not freely available. I have tried contacting Propellerheads in the past, without reply. Currently I have other things on the plan, but I will try with Rewire again in a few months time.
ZynewaveKeymasterIn the top end I can recommend RME. I have an old HDSP/multiface which has never let me down. Also if you are planning on running Vista or XP64, make sure the audio interface manufacturer has drivers for that platform.
ZynewaveKeymasterHi,
Count-in is not supported yet. It’s on the future plan.

ZynewaveKeymasterHi,
Currently you can only control VST parameters by MIDI if the plugin supports it. Try looking for a MIDI learn feature in the plugin editor.
I plan to add MIDI learn support in Podium later on.

ZynewaveKeymasterI don’t intend to add more parameters to zPitch, so it won’t get beat-slicing functionality. I read the topic you linked, and it seems that Liveslize uses a simple form of stretching on the decaying part of the individual drum hits. The algo I use in zPitch is slightly more advanced/CPU demanding.
I’ve just finished creating a small native editor for zPitch:

Clicking+dragging on the pitch band will adjust in semitones. Holding shift while clicking will adjust in cents. The band will resize to the window, so you can set a convenient size for automation recording of realtime mouse movements on the band.
ZynewaveKeymasterThe sound doesn’t seem to play in any audio track at all.
Can you get any imported/recorded sound files to play on tracks? If you open the sound properties dialog, what’s the bit-depth, samplerate and channel configuration?
ZynewaveKeymasterASIO driver status:
– ASIO sample position gaps: 9 (-96..96)Audio stream buffer errors:
– Output buffer skip count: 9This means you will hear stutter in the audio. Try increasing the buffer size, and check if this reduces the number of gaps.
ZynewaveKeymasterThere’s no activity on the bounce track meter whatsoever, but the wave does show in the track. Also, the meter does show activity when playing the actual VSTs instead of the wave.
Check that you haven’t muted the bounce track. If you move the bounced sound event to a regular audio track, does the sound play then?
ZynewaveKeymasterwhen I bounce the output to a wav, it shows in the track, but when I hit play, there’s no sound coming from my boxes
Boxes = speakers? Doesn’t the bounce track meter show activity?
when I control the plugins by midi from the track and hit play, it produces the sound, but the indicator is running behind with the events of the sounds I hear
So the events play ahead of the play cursor position? Normally it’s the other way around, if there is a problem with the soundcard driver. Make sure you have selected the proper ASIO driver. If you have sync problems with recording MIDI, try to disable the “use time stamps from driver” option in the interfaces dialog.
ZynewaveKeymasterYes, it can be improved. As I wrote previously, I will continue to work on it in the coming weeks, and that is why I announced it as a beta.
It will never be as good as any of the licensed commercial algos, but if I can get a decent quality out of it, I’ll have something to work with when designing the time-stretching feature in Podium. After this has been completed, I can start looking for more professional quality algos as a replacement.
