Working with velocity layers in multi-sample pads

[modularbeat]

Hi y'all, I'm having an issue and don't seem to be finding a clear explanation of what I'm doing wrong in the manual or in a search of the forum.

Say I record a multi-sample over one octave in 1 semitone increments at 3 velocity layers. Upon playback (using the onscreen keyboard, MIDI, or CV) the notes get mapped sequentially like this:

C4 (low velocity)
C4 (medium velocity)
C4 (high velocity)
C#4 (low velocity)
C#4 (medium velocity)
C#4 (high velocity)
D4 (low velocity)
D4 (medium velocity)
D4 (high velocity)
etc…

Assuming I'm just not setting up the pad correctly, I'm also not seeing a way to control velocity layer using CV. Hmm.

I would assume velocity is just for the MIDI input and not for CV control. No?

Assuming you are using the Load All opinion to load your wav files, if you are not seeing the files map properly I can investigate that as a bug. We did just fix a similar issue on the blackbox.

Steve Isn't what is described here some sort of round-robin? In the manual there's a reference to a file name convention, "The WAV files will be named <Filename> + “-” + <MIDI Note Number> + “-” +
<MIDI Velocity>", but other than that, there is no indication on how to use/map the velocity, or if the Micro does round-robin on its own.

I see a great opportunity to map SFZ files to Micro's presets. I might write a Python script to change the filenames accordingly and format a proper XML for the Micro.

Could you please shed some light?

Our devices do not support round robin. They also do not analyze the filename for mapping purposes. Root notes and velocity layers must be embedded into the wavtag metadata inside the file header.

I thought the Micro did read the filenames for multi-sample pads. Does this mean that micro_bundle-v3\Symplesound\Housepiano\Housepiano-024.wav has the root note embedded, in addition to be displayed in the file name, and that the file name is only used as a reminder, but the data that is read is the embedded one?

I am trying to figure out how to prepare my multi-sample wav files from the sample libraries I have in SFZ and Decent Sampler.

jocphxThat is correct. We even generate filenames with the relevant data but our samplers only look at the embedded metadata. There are several apps that can write the root note wavtag. You can also do this one sample at a time in the micro. If you load a directory of wav files with no root note data, the Micro will load them chromatically starting at C2.
