JS Stops/pauses when Editing VSTs

Sheppol_A · Post by **Sheppol_A** » Wed Dec 24, 2008 2:33 am

I've just discovered something that may lead somewhere.If I revert back to the Jam No Input mode on the track the delays go including changing the parameters in the Eq/VSTs.This is unfortunately no good to me as this mode does not play the hand programmed parts I've added to the track.

Note:In the main project I'm working on the delays are still there no matter what I do

I would have tried to have done all the parts in the JNI mode midi editor but cannot work out how to put individual drums in and I don't mean copy I mean hand place them in and the JS midi box is very small and hard to work in compared with a standard track midi editor.

Further to this left the CPU monitor open and took a Print Screen,

The delays and spikes in this project are when I move any VST parameter
in Reaper on the JS track and when I close the JS on the track.The delay does not happen when opening JS on the track after it's loaded the 1st time.

I think I have found the problem.When I made the midi track in the JNI mode and then dragged it over and hand edited it and then played it in
Drum Module Mode(DDM) I moved the midi track forward a couple of bars in the song in Reaper as I wanted a few bars of silence.This seems to have caused a problem between JS and Reaper.
There must be a sync problem between the printed midi track and the two JS drum modes if you move the midi track in the DAW.
If this helps you or anyone or a way of avoiding this in the future apart from NOT moving the midi track please let me know

Still testing as we speak but all seems ok again

Nope.It's back

But weird that when the song is now playing in JNIM it doesn't do it but as soon as you stop the song the delays are back.The delays are there in DM mode.

Also unless I leave JS in JNI mode it does not save it's configuration e.g if I leave it in DM mode and save and re-load the song I have to re-load the JS saved song as well

Here's the thing. REAPER requests the data block of a VST on many occasions, such as when you simply close a track FX window. Most other hosts do not do this and only request the data block when the project is actually being saved. Unlike simple synth plugins, the Jamstix data block is very complex and building it every time REAPER calls for it is causing the delays you noticed.

If anyone knows of a way to stop REAPER from making all these superfluous data requests, that would be the best way to fix it.

I can send you a work-around where Jamstix does not send the data block unless the CTRL key is held down. This will fix all your delays but you'll have to remember to hold down the CTRL key when manually saving the project.

Actually I have now stripped the project and added back everything and have it pretty much beat(Don't know how) but I have only one hurdle now.

In this renewed project I don't get any more delays but when I save the project with JS in Drum Module Mode and then re-load the project I don't get any drum sounds.The JS Wizard comes up when I hit the FX button on the track and I have to re-load the JS song that I have saved when I was in
Drum No Input mode?

Remembering that I have the drums as a midi file on the JS track.

I can't duplicate that problem. Can you send me the RPP?

Also, the delay you experienced is depending on the complexity of the Jamstix arrangement. So it may not be an issue in some projects.

Okay, I opened your project and JS looks fine. What exact steps do I need to take to reproduce it?

Change JS to Drum Module mode and then save the project.Then re-load that saved project.

When I open your project, JS is already in DM mode.

I tried this:

- open your project
- change JS2 to JNI mode
- save/close
- re-open project
- change JS2 to DM mode
- save/close
- reopen project and all is still well
