Impulse tracker module

wiki says impulse tracker got a "continue ADSR" feature, sounds like a nice help to make virtual channels. And it seems to be about sample soundblaster machines - but there is some very PSG special stuff in the track, non-square-wave instruments. First it starts with a pokey bass, then comes a tekkno flute - which frequency relationships are used for the waveform?

er, the PSG song is just a remake of the .it song (either from speccy or atarist scene or arranged by WYZ), Impulse Tracker has nothing to do with MSX.

@hit9918: hap has explained IT perfectly. Wink but as you said you can find help about notes, volumes, chords... or inspiration. The rest: player, music edition, instruments edition... hard work, have nothing in common.

Dreamerm42 has uploaded a youtube video. The demo seems to work only in a few msx1 VDP's

Ok, I need some "help about chords" Wink question: which chord is used for the instrument in the intro and the main instrument of the tune Smile

It is not easy to explain in a few words.

If we are talking about PSG cover:

- you can find during all the tune a type of chords usualy played in chiptunes: arpeggios.
- 1st instrument (bass intro): SW envelop pattern with frequency changes + HW envelop. This is not a chord only waves mixing.
- 2nd instrument (main tune): SW envelop pattern with frequency changes. Your hears/brain is deceived by fast changes in volume/Freqs.

I'll try to code a ROM for you includding your tests in this matter.

Weird, when I run the demo, I have a different background picture... Some kind of building and lightning...

By the way, the demo does VDP writes with only 18 cycles in between them... probably explains problems on some models.

The background was changed for posting the program in MRC forums. I updated a new version writing each 28 cycles.
Thanks Manuel.
