Wrong Octave

[bosco]

Hi.

I'm fairly new to OpenMPT and trackers in general and I've discovered something puzzling which I hope someone here could clarify for me.

I've noticed that, by default, notes sound one octave lower than the note I entered. So if I enter A-4 and hit play I hear A-3. I've also checked with my chromatic guitar tuner to ensure I'm not mistaken.

I've tried Google for an explanation but haven't had much success.

Any guidance would be gratefully received.

Are you using Samples or VST Instruments?

OpenMPT does not use scientific pitch notation. OpenMPT's octaves are inherited from Impulse Tracker, where C-5 is the middle-C.
That being said, for the correct note to be heard, your sample (or plugin) must of course play a real middle-C (i.e. C4) at C-5 for the logic to work out.

@LPChip - I'm using a square wave sample.

@Saga Musix - So OpenMPT's middle-C is C-5. Well that would explain it.

I've figured out how to remap notes under the Instruments panel so I have a work around. Might be nicer if there was a `use scientific pitch notation'' tick box under Setup.

Thanks for the info.
