Title: .41 Instrument editors volume envelop->diff. speed
Post by: LPChip on April 09, 2006, 15:12:40
If i make a nice volume envelop, and then play in the pattern editor, it has a complete different speed.

My settings (that are unusual) are as follows:

Song speed: 3
Song Tempo: 45

In the instrument tab, it plays really fast. I think 4 times as fast as in the pattern editor. Also the grid is wrong.

Actually the tempo seems to be around 150 bpm always when not playing. If you play in the instrument editor while the song is playing the tempo is the same.

The time unit for envelopes is ticks, so the effective envelope speed will be dependant on the tick rate (or tick duration), which in classic tempo mode is defined by Txx.

My guess is that if you play an instrument in the instrument tab while the pattern is already playing, it will sound the same as when played from the pattern editor, because the Txx playback speed will already have been set to the correct value. But when playback is initiated from the instrument tab, some other Txx value is picked up.

I'm looking into what Txx value is used when playback is initiated from the instrument tab.

I'll check it out tonight.

I'd like to point out that the same thing happens if I put the pattern editor to jam mode and play there. Also the same 150 BPM thing.

Nevertheless, the song plays fine in other players and when normally playing.

I had to adjust the envelope while the song was playing to get it right.

What do you mean by "jam mode"?

If you press the record button (CTRL-Space), you cannot enter notes, but they are being played. (Bytheway, I now believe that entering notes also plays them wrong:P)

Yes, in any situation in which the instrument was played but the song was stopped, we would have used the wrong tick duration, therefore screwing up envelopes.

Confirmed to be fixed in any situation I could think of. Thanks Rewbs!!! :)
