Midi import discrepency notation

Postby Michel Camire » Sat Nov 22, 2025 12:48 am

Hello ,

The 1st picture shows a 4/4 motif with its 4th beat being a quintuplet g,f,g ,a,b .When importing it in Gstomper Producer this 4th beat sounds correctly as a quintuplet but as you can see on the picture the 1st 2 notes are written as a mjr 2nd harmonic interval ; can you alleviate the confusion ?

Thanks!

Hi Michel
Could you please send me that midi file via email?
Eventually, the timing is not straight in the midi file and it falls into quantization. With the file I could check the case.

Hello ,


Any development for this midi discrepency ?

Thanks

Hi Michel
Not yet, sorry. Was traveling last week. I'll look into it this week.

Hi Michel
You already answered most of it in your other post at viewtopic.php?f=9&t=1023 .
I ran a few tests, and can confirm that the importer works as expected.

All you have to do is to turn the quantization off while importing.

When you switch to edit mode in the poly grid, you can show the micro steps. You'll see that the 2 steps that look like an interval are actually 2 notes that are shifted by micro steps.

If you keep quantization on, then the importer tries to find the best possible fit within the giving 16th or 32th (picked dynamically, depending on the content).

All G-Stomper apps, incl. Producer, are use step based sequencing. In other words, there is a strict quantization on the given steps.
However, the AI response you posted is not 100% correct. Steps are neither always 16, nor are these bound to a specific timing.

You can create patterns of a size between 1 and 128 steps.

https://www.planet-h.com/gstomper/docs/ ... part18.htm

The time of each step can be between 1/8 note and 1/64 note.

In G-Stomper Producer, you can combine different setups per track.
By combining multiple tracks, you can create complex polyrhythms using the step sequencers.
Of course, that's different from simply playing them in one track without quantization. It's a different approach with equal or similar results.
