I took my cards out of the DAW, and placed them on a Magmafied laptop. Now I'm using it as outboard synths, triggering notes via MIDI on Ableton (on the DAW), through the MIDI port of an RME Multiface card. My problem is with hanging notes, most particularly with the Pro-12. It seems to happen quite often, especially if I jump the project to another locator without hitting stop, but not only on that case.

I believe that when you hit stop in Ableton it sends an all notes off to every port, but it doesn't seem to work. Even if I use my MOTU MTP AV, which has a dedicated PANIC button, it doesn't stop. What I have to do, is to reduce the poliphony of the Pro12 to zero, and 9 times out of 10 it works.

So, I'd like to ask you people if this is a common problem, and if so, how do you work around it? Is there a way to reset MIDI on SFP?

Thanks in advance,

T

it's not uncommon, but there are various possibilities.
You may have a midi loop in your routing, which can be overlooked quite easily.
The same, but not due to routing - instead the system acts as if there's a kind of software 'leak' temporarily.
Sequencer midi source and destination seem to play a special role in this. You probably don't need them anymore, so they could be removed from the routing window.

Possibly you need to start from scratch if the project document got messed internally.

As recently reported a hardware related version of the problem may exist (easy to check).
Send the DAW's midi output to an arbitrary device that can midi-through and the output of the latter to the Magma based Scope card.
Of course you should have checked your cables before all that :wink:

cheers, tom

also, use the midi monitor to see what is actually being transmitted.

I had the same solution by 0'ing out the polyphony to restart the DSP's. Funny thing is that I exclusively use Solaris and Modular now and I haven't had a hanging note since. When I did have the problem it was always one note only, which leads me to believe that Modular and Solaris were thoroughly thought out in respect to MIDI. It only happened to me with Minimax, and Pro-12. Go figure.
I used MIDI monitor also, but it always showed me the info prior to the note which hung.

There's a "Reset MIDI" menu option in Cubase which seems to do the trick. Is there not something like this in Ableton?

Hello again, and many thanks for your assistance. I've been working on other projects (that don't hang), but today I'll get back to my problem-child...

Anyway, I have checked all MIDI cables, and AFAIK there are no MIDI loops: it's DAW MIDI out > Scope MIDI in > Scope synths & Scope MIDI out > Korg Prophecy. I only have this problem with the Pro-12, even though I'm using a couple of Minimaxes and a Modular as well. I'll try routing the DAW MIDI out to the Prophecy and through to Scope, to see if it helps...

As for the MIDI reset switch, I can find it in Cubase, but not on Live. However, when I press the stop button when stopped, I see all port LEDs flash in the MOTU MTP, and in the RME, so I believe it's sending an all notes off. I'll check with Ableton, and also with the MIDI monitor and I'll let you know. IMO, there should be a panic button on every synth!

BTW, I like the way the Pro-12 sounds, (especially @ 96KHz), but I find it very hard to tune! I could use a plain semitone/octave switch for the oscillators, but that wouldn't fit the retro-modeling thing they have there... Maybe we could have a transposition switch on the Live-bar! Would be a time-saver when layering different synths, triggered from the same MIDI track... Also, I keep hearing about Solaris, and I am very curious to try it out. In your opinion, is the "light" version of the synth equally glorious?

Thank you all, I'll keep in touch!

the pro12 is not really designed to run at 96khz(afaik), because like the minimax, the filters are oversampled......

changing samplerate or voices always needs time, which at least while playing live you usually don't have.
I had a lot of midi hanger probs with minimax while developing the StepSequencer. That's why I integrated a midi reset function, which also works automatic if desired. It is available as separate device with the MidiToolBox. If you need only some devices from this package and not all, just drop me a mail.

I merge the midi keyboard device (with the other input) and press the key.

Hello again. I have tried and tried, but the hanging is there. Mind you, I'm working at 48kHz, even though I have managed to get Pro12 and Minimax running decently at 96K. Sounds good, but I think I'm just asking for trouble doing that (like garyb says, the oversampling in the filters might be too much).

I appreciate wolf's offer (PM is on the way), and he's obviously right noticing that we need a fast way to reset MIDI when performing live. Maybe I'll take the opportunity and get me a few other devs. And also to Lima, that seems like a good idea, I'll try it out this evening.

Many thanks to you all, and all the best,

T

Hi Tau, remember that Minimax and Pro-12 has an internal oversampling, so there's not an apreciable advantage in using them at high samplerate.
