I'm trying to work out some timing stuff and I'm having trouble seeing how the speed and BPM options work together. I assumed that the value for speed was the number of ticks between consecutive lines, which would then play at whatever the BPM was set to (this would, of course, change the duration of each 'tick' as the BPM changed). I wanted to use this to do triplets, by setting an instruments volume to (for example, with speed = 3) | 15 8 1 0. (4 'ticks' per note instead of 3, so for example 4 quarter notes = 12 ticks, and 4 ticks goes in 3 times, giving a 3-note tuplet). However, it seems to me this doesn't work.
Perhaps someone can help a newb and explain to me the true relationship between these values?
Thanks! Also, what's the relationship between BPM and the 'frames' in the instrument sequencer? (see my example above about triplets) Is it 6 frames per BPM at speed 6?
For the latest beta: Find [Tracker] --> [Engine Speed] on the toolbar and you should find two selections: 'Default', 'Custom'. Click 'Custom' and you will be able to use a custom engine speed based on a per-module basis.
For earlier versions: It is the engine speed determined by the NTSC/PAL settings. NTSC's default engine speed is 60Hz while PAL's is 50Hz.
[quote=xolroc]I never knew there was a custom engine speed! Is it saved in .ftms?[/quote]
Yes.
Also jsr said that modules created with the coming stable release can be loaded with 0.3.0. if no new features are used. Custom engine speed might just be one of those.
Thanks for the info! So let's say I've got a speed of 6 and a tempo of 106, and a frame rate of 60hz (NTSC). The true BPM is 106 since the speed is 6, I assume every 4 lines is a quarter note, so an eighth note is 2 lines, or 212/60s, giving 212/60*60 = 1 eighth note per every 17 (approx) frames. Triplet eighth notes should then be one note every (17*2/3) = 11.3 frames... if sixteenth notes happen every 17/2 = 8.5 frames, this means that 3 notes on three consecutive lines with a delay of 3 frames and then 6 frames for the 2nd and 3rd notes should give triplet eighth notes? Hmm... that sounds about right when I test it out... so my math seems to be correct!
