Nektar Impact GX49 issues with usb midi hub

Jan Dobrovolný — Tue, 07 Jul 2026 07:37:23 +0000

Hi,

Im currently trying to connect my gx49 via usb midi hub (CME H2, Kenton) to control my 3rd wave desktop module but Im running into note hanging issue.

When I play note quickly and use pitchwheel at the same time notes tend to get stuck (remain playing) after the key is released, other notes can be played while this happens, the note stops playing only after the same note is played again, this happens also in daw when I tried to play the keyboard through the CME into Ableton.

Ive tried both the CME and Kenton hub, same thing happens on both. Also tried different midi keyboards, even another Nektar gx61 and only both of those Nektar keyboards created this issue ( I need to use this one because of my limited space in my case).

Ive manage to get it working only when I ran it like this:

Nektar -> usb C ABLETON -> usb C CME -> 5pin 3rd Wave

This makes no sense to me since I read that Ableton is not altering midi notes going through.

Did anyone else encounter any issues trying to use Nektar midi with usb hubs?

Any suggestions what this might be about?

Thanks for any inside.

Roland MIDI Equipment problems with MIDI2.0

Henk Zwart — Tue, 24 Mar 2026 12:05:59 +0000

Good Day

I have the following Roland products that have issues with MIDI2.0.

2 x Roland Fantom XR modules and 1 x SonicCell module. In the MIDI app, it will be registered all as Fantom units. It does not recognize the ID and therefore personalizing does not work to correctly identify the MIDI API.

The other MIDI interfaces are working correctly:

2 x Korg Kronos, 2 x Korg M3 and Roland Integra 7

M-Audio Midisport 8 x 8 is seen for 1 x Korg X5 and Roland JV1010 but Cubase pro14/15 still crash because of Midisport unit

All the above unit work properly before MIDI2.0

Note: Roland Fantom XR and SonicCell drivers are not digitally signed and were modified to work with Windows 10 removed link

When will the M-Audio Midisport driver clash be sorted out?

Is there a workaround with the API driver id confusion?\

Regards

Henk

USB Midi Host adapter

John Munro — Wed, 04 Mar 2026 18:16:05 +0000

I wish to setup 2 keyboards in a master/slave configuration. Neither keyboard has midi connectors. If I connect a USB Midi host adapter to each of the usb ports on the keyboards and then run a midi cable from midi out on the master to midi in on the slave will I be able to then send midi from the master to the slave.
Tks

Testers for a powerful App that controls Windows with MIDI devices

Jamie Crowther — Fri, 30 Jan 2026 23:08:16 +0000

I’m looking for a small number of Windows users to participate in a private test of MIDI Command Studio — a desktop utility that turns MIDI controllers into configurable control surfaces for Windows applications.

The app maps MIDI notes, CCs, and faders to keyboard shortcuts, macros, and app/system volume, with per-device presets and LED feedback.

I’m inviting 5–10 experienced users with MIDI hardware to help validate the install, device handling, and core workflow before a wider release. Testers will receive a free license for the full version.

It's already quite a powerful tool for people who want to control windows with their MIDI devices.

If you’re interested, please reply or DM with:
– Windows version
– MIDI controller(s)
– Typical use case (e.g. editing, streaming, productivity etc)

New Behringer K2 MKII Needs Keystep with Hz/V an S-Trig

Bruce — Mon, 22 Sep 2025 23:16:46 +0000

Hi. It has been a while since I have posted anything here. I may not have posted anything at all. I have a question with my new Behringer K2 MKII and the Keystep 32. When I use the Arturia MIDI Control Centre and change the standard from V/Oct to Hz/V and R-Trig to S-Trig, and run a MIDI cable to the K2, it all works as expected. When I use V/Oct and R-Trig on the Keystep, it does not work as expected. However, when I look at the MIDI signals there seems to be no change in the data. I am not using the CV out and Gate out for anything. I am curious as to how this works.

I know there are things you can do to make the K2 respond to V/Oct and R-Trig but I would also like to be able to convert the information on my own using something like miRack and VCV Rack - editing MIDI signals as needed.

Roland SCXX vs Yamaha MU15 BEST?

Im using a MU15 and a 2x2 midi sport for my 1 man band. Im looking to bau a backup sound generator in case of MU15 death.

Does a Roland SCxx sound better than the MU15? I love the sound of my wifes Roland E66 piano!

MIDI Powered-Unpowered Devices

Jaroslaw — Mon, 05 May 2025 21:35:33 +0000

I was disappointed with MIDI devices recently. I tried to connect my laptop and MIDI Solutions Quadra Thru V2 via Emu XMIDI 1x1 USB/MIDI adapter and the my other 4 synths. Quadra Thru is a brilliant idea on which this device is built. It needs only 5v which MIDI system is based on.But Emu adapter doesn’t provide such voltage. It doesn’t provide any voltage or just 0.0002v. I haven’t been aware that passive and active MIDI devices exist. MIDI is MIDI and connected devices should work. But they don’t… How could the renowned company, Emu, build such a poor device? I have got two of them. Fortunately, I own M-Audio adapter which provides 5v.

Roland SD-35 MIDI Player Replacement?

Mike C — Tue, 18 Mar 2025 22:22:42 +0000

Does anyone know of a satisfactory replacement for the Roland SD-35 MIDI player (pictured below)? I'm on my 4th unit. As they are out of production, I'm looking for a replacement. Any suggestions for a hardware general MIDI player that is easy to use on the gig? (not looking for a laptop solution) Thank you.

More than one CC-message per USB-poll?

Oor Tone — Wed, 05 Feb 2025 14:40:52 +0000

If I understand correctly the polling rate on USB-midi communication is usually 1 kHz.

If a USB-midi device is sending CC-data over USB, let's say a knob is turned swiftly, quicker then the polling rate, then will all CC:s in the same poll be considered arriving at the same time in the USB-host (usually a computer), or are they timestamped so their relative positions are kept, or are all but the last CC per poll conisdered relevant?

Multiple CC messages at the same instant seems pointless in almost all situations as opposed to simultaneous Note-Ons which makes sense. But how is this handled by the protocols?

The question can be reversed. If a DAW has higher timing resolution than the poll rate (Logic as an example has twice the resolution @120 bpm) how is this timing handled when sent out to a USB midi-device?
