Subject:Piano roll and time signature
Posted by: JamesHE

I'm new to Acid and MIDI in general, just working with the 5.0 pro demo right now. I would like to start using acid as an arranging tool. I do not have a midi input device, so I'm stuck experimenting with the piano roll for now. i'm a total midiot. :P
Is there a way to have the Piano roll not be in 4/4 time? no matter where i set my time signature, or how I edit the roll, the actual loop that gets painted on is in 4/4. What controls the length of the midi event? how can I change the time signature (how it is displayed on the piano roll). I understand how to change it on the time line in acid, by the midi events aren't working out.

Hmmm...the MIDI track properties window's beat ruler changes just like it does on the main timeline, but the MIDI event itself paints out as if it's like 4/4.

I did notice that as the MIDI track grows in length, the event is also similarly longer before it loops.

This would obviously put a damper on anyone seeking to use ACID Pro to loop MIDI using alternate time signatures. This may be a bug. Can anyone else repro?

Looks like a bug to me. I can’t get MIDI to do anything but 4/4 loops.

"I can’t get MIDI to do anything but 4/4 loops."

That's the only time signature that matters anyway, so it's not a bug it's just a workflow limitation because, 90% of the top hit music is in 4/4. Take your 3/4 and 6/8 swings out of here, "Acid Rocks!!!". :-)~

yeah this is really lame.

I found this in the help files:

For loop tracks, the software assumes that each beat is a quarter note. When you choose a time signature in which a note other than the quarter note receives one beat, you can see inconsistencies in loop lengths on the timeline.

translation: loops don't work right in odd times.

so here is the work around; once I get things laid out in the piano roll like I want (ignoreing the extra 8th notes) Using the pencil tool I drag out the measure to the correct grid line - which it snaps to - then release the mouse and repeat. This really means a lot more steps. The time/tempo markers work well. I could really really really use those in Vegas!

Well us aging progressive rockers like to write in 7/8. ;-)

Render to new track also doesn’t seem to work properly either. When I rendered a MIDI loop in 7/8 it came back as a one-shot. If I try and make it a loop of 7 beats ACID incorrectly sets the tempo of the loop to 200BPM.

I even went into Sound Forge and manually set the ACID properties to a loop of 7 beats and ACID still thought it was 200BPM. If I highlight only the first 4 beats in Sound Forge, the ACID Properties windows shows 200BPM. It seems to be a limitation in the ACID metadata since there is no way to tell ACID that 7 beats equals one measure in the properties.

So it seems that ACID is incapable of detecting anything that doesn’t have 4 beats per measure. :(

Ok that was the secret. 7/4 works just fine when you Render to new Track (MIDI looping is still broken). So it only works for rendering when a quarter note gets one beat.

JamesHE: Try using ACID's paste repeat feature. Copy the event (once it's correctly drawn) to the clipboard, then use CTRL+B with the "end to end" option. (Make sure you also place the cursor where you want the pasting to begin.)

I have fallen into doing just this, similar to how I would use Vegas. The only problem is that if I edit the MIDI, I have to repaste everything. Not the end of the world, just potentailly confusing!

Thanks for the input!

DO you know if it's possible to set up a new project in 6/8, and then use loops done in 4/4, and have them work in 6/8?

answer's still no...they'll work, but they won't magically convert to a different time signature. But who knows, might get some interesting results. This does seem like one of those things you coulda just tried, though...

Well...next time I'll try something out before I inquire about it via this medium. However, being at work and not in the studio, and not having done the "chopping" routine before, and considering the convenience of the e-mail thing and all ... All apologies.

no worries, paloalto, you got one of those type of jobs too, eh?

I bet Sony hopes my boss gives me more work soon...
