  1. I may try another tune with it ... and also some double POKEY stuff to see what else may be possible. The Ms Pac Man opening may suit.
  2. Other possibilities in this setting: Using double POKEY, setting up a 1.79 mhz channel on the first channel each POKEY, then having the third channel each POKEY add a harmonic, or turn on the filter for each channel. It would require downmixing to mono from stereo but might produce interesting results
  3. Here's a test. AUDCTL=$60 00 and 02: $AF (1.79 mhz) 01 and 03: $A3 (standard square wave) The ultrasonic frequencies at max volume make the triangle wave. There are several problems with this technique: The resultant triangle wave is quiet, so the volume of other tracks must be lowered. Frequencies below $40 introduce a high pitched artifact Frequencies above c6 are out of tune, meaning you have a 1 1/2 octave range that can be effectively used. Binaries attached plus a note table. The note table varies the two frequencies in 0 and 2 off by one step. The table used for the "croissant" wave (AUDCTL=$64) is better in tune but not an option here as it dips into frequencies below $40 to make the notes in tune, and introduces the high pitched whine. dk-title.asm dk-title.s dk-title.xex AUDCTL=$64 AUDC1=$AX AUDC3=$00 optimal.txt
  4. Back at it again ... found a new setting that was documented by the late @analmux: AUDCTL=$60 (1.79 on 1 and 3) Play $AF on first and third channel The idea is, by setting maximum volume ($AF) on first and third channels, the clipping makes a resonant frequency of a NES type triangle wave. The note table used is identical to the "croissant" wave AUDCTL=$64 setting and the same caution applies: Lower frequencies (beginning at $40) will introduce a high pitched whine as the source frequencies come down into the audible range. I will try a test tune.
  5. You should now do a port of Pepper II and call it Diablo
  6. A couple of caveats here: The RMT emulation in sa_pokey.dll is dodgy and not to be trusted. I think @VinsCool was working on a project to enable these custom modes into RMT. Also, the distorted guitar sounds I used in odyssey do not lend themselves naturally to pitch bending, because the modulation frequency on each note is not exactly linear.

    I'm back ... been away for a bit but I will be working up more music for this.
  8. Thanks! Been away for a bit, and I'm pleased that's the case.
  9. The issue with HOKEY is of course, emulation of these features. Currently, E.X.O. (which uses two tone mode and other nonstandard settings) does not work on HOKEY as far as I know. If this can ever get sorted, we may have a true alternative.
  10. Question: Will Atari license Bob Crescenzo's Bentley Bear Crystal Quest for the VCS? It'd be cool to see this game officially acknowledged by Atari and added to the canon.
  11. Well, how about ... Atari officially licenses Bob Crescenzo's Bentley Bear Crystal Quest on the VCS?
  12. I was inspired by the music for the similarly themed level on Blaster Master when I did the music for the organic Area 4 on E.X.O.
