MIDI note velocity issue

Unread post by jazzcabbage » Sun Feb 24, 2019 8:14 pm

Hello!

Has anyone seen this issue with their MODX? Basically note velocities over say 88 are not being recognized by the MODX via MIDI. If I lower the note velocity it plays. Seemingly random, but more often than not.

Tried different DAW's, MIDI cables, MIDI interfaces. I have narrowed it down to the MODX. I have also performed the latest firmware update to no avail.

Is there something I'm missing in the settings interface?

Hi. Can’t say I’ve noticed that on my Montage, but would need to check specifically (and I’m currently away from home). Most unusual.

In terms of creating a “bug report”, I’d create a “stair case” of notes with increasing velocities and obviously record the outcome and send to Yamaha

It’s quite possible you have a faulty unit. If so I’d demand a replacement.

Thanks! On another forum someone mentioned the multi performance instruments and the midi channel out selection in the DAW needing to be ANY or at the MODX setting MIDI I/O mode from multi to single for that instrument -that worked btw-. The ANY setting at the DAW has not worked as anticipated but I'm trying to see as to why it's not working from the DAW -Cubase and Reaper-.

I see what happened. I was working with older material that was originally recorded using one MIDI channel.

Playing that back to the MODX/Montage with a multi performance instrument it only sees the one channel. Even selecting ANY MIDI Out will not help. When recording MODX/Montage sends multi performance velocity parts to the DAW to be recorded on the same track but with separate notes for velocity -in this case- on separate channels.

If the original piece was not recorded in this fashion it's only going to send the one channel velocity data to the MODX/Montage. Thus the dead notes...

So I'm guessing with older MIDI recordings the only option is to choose MIDI I/O Mode = Single?

nope - just choose that option (single) under the Attribute button on the main page (Category). No need to change MIDI mode at all.

Basically in a nutshell I had an old project that the MIDI was recorded using a single MIDI channel.

I wanted to play that back with the MODX instead but found notes dropping out. That was due to MIDI I/O Mode set to Multi and each instrument in the performance was set to handle different velocities and those were set to receive data on different MIDI channels.

So basically the choosing MIDI I/O Mode to Single does work in a pinch for auditioning but you loose the full subtitles of the velocity triggering samples. In this case it was a piano sample.

The simplest way around this for an old piece to take advantage of this is to copy the one OLD MIDI piece to separate tracks. For this one it was three. Then assign each the corresponding MIDI channel number for each of the instruments in the MODX performance. Run the outputs of the MODX into a single track and voila it ends up sounding like the original MIDI piece was recorded as a multi-instrument.

Hi,

So sounds like you have solved it now?

I think I am having the same issue:

I have my motif connected to the MODX through my DAW workstation (midi). When I play the motif, and send the midi outputs to the modx, I have an issue where not all notes create sound on the modx at certain velocities. This is only evident for modx sounds that are "multi". The "single" sounds work fine. All works fine if I play the modx. Any idea what's going on here? Is there a fix or workaround?

My goal here is that I have an MODX7 and my weighted Motif XF is just a better playing experience when I am laying down piano.

The MODX includes a new feature, multi-part single instruments. This allows an instrument to have more than 8 elements. However, the different parts are assigned different MIDI channels. So you need to keep this in mind when using these sounds. If you're playing a multi-part piano, for example, Part 1 may only respond to a certain range of velocities, Part 2 may respond to a different range of velocities. So getting back to the OP, it wouldn't be that "note velocities over say 88 are not being recognized by the MODX via MIDI" -- rather the sound assigned to Part 1 is designed to only play velocities up to 88 on MIDI channel 1, and higher velocities (which trigger a brighter piano sample) are in Part 2 just waiting to be triggered... on MIDI channel 2. Settings to account for this have already been mentioned, I'm just explaining why it is. Another way you can address this is to simply put a single-part Piano (or whatever sound you need) in Part 1, that should solve it for you as well. You're just limiting yourself to sounds that have no more than 8 elements.
