Single cycle waveforms in sampler

Hi. Thanks for having me….

Just wondering if anyone might have a fix for tuning issues when using the sampler, specifically with single cycle waveforms.

The keyboard does not track the tuning correctly over the keybed…I get atonal nootes and repeated notes.

Thanks!

Do you mean that your samples are only a single cycle long, or that they are composed of many cycles of a single waveform? I can’t really imagine that a sample with only one cycle can be retriggered accurately enough to make a clean pitched tone…

#3

Single cycle waveforms are just looped so that they produce a constant tone. It works fine in that regard. It’s just not in tune as you go up and down the keyboard.

#4

Can you attach one of the single-cycle sample waveform files you are using so we can try it out?

Hi … It’s the one titled DMS Classic Analog.

When you try it , do so across various octaves … when I go up one octave it starts freaking out.

One potential problem I am seeing is that the original wav file is 24-bit, 44.1kHz. The Microfreak requires 16-bit, 32kHz wav samples.

What do you mean by “requires” ? Do you mean for optimal performance? Because all the wavs Ive used are standard but function in some shape or form on the mf.

#8

The Microfreak manual says “Your MicroFreak will store the imported samples as 16-bit, 32kHz, mono samples.”, but maybe MCC does the wav format conversion internally before it sends the data to the device, so it could be the original wav format isn’t important. Maybe you can ignore what I said…

#9

I made a new longer wav in Audacity by merging twelve of the single cycle waveform together and exporting it as a new wav file. This one actually keeps tune across the keybed. It’s possible that MCC can’t convert or Microfreak can’t loop wavs as small as single-cycle accurately (I believe one of my Roland devices had the same limitation).
