AU issues

Post by qaratechop »

Anyone else having problems with AU effects Frekvens and RP-1 in MTS?

Frekvens doesn't seem to take in any audio when added to an effects chain, effectively killing the audio for that track.

RP-1 works okay about one in 50 times, but most often doesn't load its interface (looks like just a blank grey rectangle) and again kills the audio for the track it's slotted into.

These AUs work for me in another host (AUM).

While I'm here, I also can't get any syncing in MTS out of the app Patterning, neither via MIDI clock or IAA sync. Once again, works okay both ways when hosted or sync'd from AUM.

Sorry, would like to try those out, but I (amazingly) don't own either of those apps. I'm actually revisiting MTS now after several months (and a new iPad!), so I'm happy to find the AU support. The roster of AU instruments is expanding slowly, but we still need more. I've had Arturia iSEM, Enkl, and Ruismaker working beautifully. Even the presets are all there, and after exiting MTS and coming back, the AU instrument reloads automatically and is ready to get to work!

I have no doubt there are some problems with some other AU's, but those can often be on the side of the instrument app not implementing AU properly, as well.

There are problems with Ruismaker when using MTS as the host as well.

Ruismaker has settings to use standard GM drum mapping and ignore CCs, but when enabled these options are somehow over-ridden by MTS.

I've contacted the developer of Ruismaker who said these issues weren't found during initial testing but have been confirmed since then, and only with MTS apparently.

Additionally MTS doesn't seem to remember kit changes. Rewind a song to the start and it will always revert to the default Ruismaker kit.

The AU itself is responsible for the kits. MTS sends various MIDI messages when transport starts (to stop any pending notes, to make sure the controllers match the values that appear in the editors etc.). Looks like RuisMaker changes kits in response to one of these messages.

I'm also having AU issues.

AUs will not change presets. As soon as I press play it reverts to default preset. This issue in Phasemaker and Poison 202. Poison 202 does not playback properly. Instead of playing a full note it plays a blip then cuts out.
I deleted and redownloaded MTS, but to no avail.

The same AUs work in Auria.

This wasn't happening a few months back. I'm on a Mini 2.

Thanks in advance.

So the problem started when iOS or the AU changed.

Please try again, and then send a report (http://www.multitrackstudio.com/contact.php describes how to do this in the desktop version, it's basically the same on iPad). Perhaps there's something interesting in there.

Thanks for the reports. I can't see anything unusual, so I'll add the issue to the list for investigation.

Do you still see this with the current version of Poison 202? I doesn't happen here.

Thanks for the update. However I have found the same issues with a few AUs — Phasemaker, Troublemaker, Wavegenerator ... they return to the default preset.
Also had problems with some IAAs like iOdessey — no sound.

Thanks

So are there any AUs having this problem that are not from Bram Bos? As far as I know only his plugins have this problem with MTS, and MTS is the only host that his plugins have this problem with.

Wavegenerator is PPG not Bram Bos.

Edit: no I checked Wavegenerator again and it seems to be fine now. So just Bram Bos apps for now regarding AU.

Edit:All IAAs fine except Korgs Odyssei. But I couldn't get it to respond to midi in Auria either...

Perhaps it responds to one particular MIDI channel only?
