      It's a good one. I stated this already in the comments under the video.
      I wonder, if he could manage to add a 3rd voice.

      As it isn't possible to have 2 tone and filter PWM at the same time, why not having a closer look at gen. 2
      It is very good in the resolution and gains good vibes on the "Acoustic Guitar" range.
      In this vid you see gen.2 at one channel. Then the melodic voice build on 3 operator PWM filter sound, and the percussion channel ... (not just playing hi hats)

      The really challenging stuff for POKEY and Musician is to create tunes that put all the stuff into one tune with nice transitions. Some Tracker that allowed changes in the instruments, as it is regular given in synthesizing software, would allow to play tunes for hours and will never sound the same.
      dxRMT can do that on the tracker command side, but it is too buggy and crashes quickly.

      SID has it's unlimited power:



      This is mindblowing yet simple approach. Pokey would not do this.

      @jhusak

      Did you ever realize what my work on POKEY's sound means ?

      Contrary to SID, POKEY has some analogue behavior when it comes to PWM.
      POKEY also has this 3,4MHz oscillation sound.
      You could write a program that uses the "resulting" shapes of the 3,4MHz sound.
      It is possible to create forward and backward sawtooth....
      So you don't need to update POKEY at "15kHz" sampling rate. 50Hz can be enough, if you use some Program that analyzes the Waveform to replay. Is it ascending just set forward sawtooth, is it descending, set the backward sawtooth...and so on...

      Also... to reproduce a human voice, you need some sawtooth waves....
      High PWM sounds also act like "Triangle" waves....



      Short but efficient ... RC Image included....

      @emkay You think I do not know? :) Alley Cat was the best demonstration what Pokey can mimic.

      Not sure what you know.
      Alleycat FX is nice, but it is some random noise that reminds of things.
      The Dog bark is the greatest part in there.

      I'm talking about "non random" sounds. You guys still don't understand that my work is built on full wave control.
      Waves that can beused in melodical steps. It's not my fault, if you don't share the same taste for music.
      But you really should have understood the potential in there...

      The restrictions still were the limits of RMT...

      Alleycat uses one "FX". The real challenge is to set a sound and to bring it to different notes...

      @rbej1977 Such a statement only can come from people who don't hear frequencies above 3500Hz...

      On the other hand.... Does this sound "squealing" to you ?




      Fun fact about this one: It uses PWM on 3 channels (3 synth voices) . The interaction of the channel waves suggest 6 channels.

      No. This statement only can come from people who have good taste.

      @rbej1977 with all your "good taste in music", what should I propose to people who don't know the 8 bit scene, to make them liking the music they will hear ?

      I know you won't get it.

      Let's have a closer look at THIS tune.
      It partially squeals a little too much for my taste, but the whole replay time, you hear "Samples" produced with the sound generators of POKEY.
      It cannot get more perfect as RMT doesn't allow to set a musical feature and POKEY's registers at the same time.
      It plays sounds that were "outside" the 8 bit range. Wave FX suggest not just PWM used . There is a lot more going.

      Dude, this stuff in #19 is well-crafted. Good job.

      Share some xex please, so folks can play it on a real shit.
