I like some artifacts with my stretching. But then you missed something
Albeit crude, here's one technique that does:
pitch shifting without affecting sample length and
time stretching without affecting pitch. I'm not in front of my MD atm, so please excuse any errors in the following description:
1. Choose a track loaded with a sample and set RETRIG to 127, retrig SPEED to roughly 20-30 (?).
2. In the LFO menu, assign a rising linear ramp to START. Set trig mode to TRIG. Set SPEED to a fairly low value, and depth to 127.
The sample will now retrig at a fairly high speed, but the LFO will make the retrig point move throughout the sample, while playing. You will need to adjust LFO speed, LFO depth and retrig time to get a useable result.
- Retrig speed governs the "size" of the chunk to be played before the next retrig, ie the coarseness of stretch.
- LFO speed governs the speed of time stretch - the lower the speed, the longer the sample, and vice versa.
- LFO depth governs the size of the jump from one retrig point to the next. At lower values, it will only play through parts of your sample.
So in effect, you can do pitch shifting with fixed length by adjusting the pitch parameter. Since the retrig and LFO settings govern the length of the played sample, the pitch parameter won't affect length.
You can also do time stretching by adjusting the LFO speed. This parameter alone will determine the length of the sample.
Using other LFO waveforms you can do non-linear stretching:
- An exponential ramp will eg let you play a loop with falling or rising speed. Start off with 300bpm and end up with 20bpm.
- A combination of different LFOs (eg LFO mix parameter to 64, combine waveforms) will give quite unpredictable sample playback, falling and rising speeds
- The random waveform will play back your sample at randomly selected points in the sample.
And... it's a good thing you like artifacts
