Yes, this is maddening (especially when EVERY sequencer in the 1980s could do this correctly, including those in DOS). Plus, it makes me look like I don't know what I'm doing. Imagine this happening to you.... a client brings a chart in 12/8 with a metronome setting of dotted quarter = 120. I have it set up ready to go... but client sees tempo set at quarter note = 80.
First thing out of the gate, client thinks I have the tempo set "wrong". Now I have to "prove" I have it set to come out right... So I start the long explanation on how the program bases the tempo on quarter notes (or two 8ths, not 3 like we need here). I show the calculation (120 divided by 3 times 2) that gives us the correct tempo BUT must display the wrong tempo marking to make it come out right.
Next, it's off to the net to find an online metronome set to click at 120. I start Studio One, then client hears they are both clicking at the same tempo, but still is not convinced, so....
Next it's off to Finale, where I set up the tempo as dotted quarter = 120 (because Finale is from the 80s, it can click compound meter correctly). Then, export this Finale to midi file. Then import it into Studio One and presto, Studio one will give the same incorrect tempo marking I already had to make it come out right, quarter = 80.
NEXT... Now that the client understands why it is set wrong to be right, I now have to answer the question why I, as a professional, would use a program that can't handle the most basic of basics, day one stuff when you first start studying music, tempo. So I explain, back in the 1980s EVERY SEQUENCER did this correctly. 30 years later, the ONLY DAWs that do this correctly are Digital Performer, CuBase, and ProTools (and Finale, not a DAW though). This is because these programs were created in the 1980s with the help of professional musicians, and are/were "musical".
Now after 40 minutes of wasted time on this, we start the project. Do they come back? Nope, who wants to work with someone doing all these work arounds "wasting" their time while on the clock? That's what the client leaves with as their impression of me (thankfully compound meter stuff doesn't happen too often).
Please, correct this error. Be the ONLY DAW created in modern times that does this correctly.
PS - I'd love to work with PreSonus to get this set the way musician need it to be musical. Should be very simple to correct.
