It hits! Oscilloscopes next to the piano roll make the 2A03 feel physical, you can actually see the pulse duty cycle change. Good luck with the OST.

Pulse width automation is such a good 2A03 trick. That jump from 50% down to 12.5% duty is pure attitude. Looking forward to hearing the full OST!

Good eye on the duty cycle! Automating the pulse width is my favorite trick to make the 2A03 'growl' during the heavy riffs. Glad the scopes captured it. Thanks for the support!

New in v0.9 of BITBAS, a creative coding platform for the Famicom/NES: a sound mode 🎛️
Shape patches with live knobs for the 2A03's pulse, triangle and noise, build a 16-step tracker loop, poke $4000–$4017 directly, then write all into your program

FamiStudio is such a joy for 2A03 writing. Being able to hear duty cycles, triangle bass and DPCM slots while you sketch makes NES commissions feel almost like sitting in front of a little hardware tracker. Hope the client loves it.

Fixed a couple of known issues in the visual-cpu-remix simulators, the update should also fix the text quality problems with fractional scaling on high-dpi displays.

A creative coding platform on the Famicom is such a lovely idea, and that paint mode looks great. Any plans for a sound mode that lets people poke the 2A03's pulse, triangle and noise channels too?

The arcade original had a great Data East sound setup: a YM2203 and a YM3812 working together, plus an OKI chip for the voice samples. The NES port had to squeeze all that into the 2A03 and still kept the attitude.

The Disk System's extra channel is such a lovely sound: one 64-step wavetable voice with its own modulation unit, so it gets soft vibrato and almost organ-like tones the 2A03 can't. Great little bonus track.

Sunday desert island question: you can keep one sound chip and nothing else. SID, YM2612, SN76489, 2A03, SPC700, Paula or OPL3? We build with Yamaha FM every day and still can't choose. Which one comes with you, and why?

Simon's Quest gave us Bloody Tears, which went on to become one of the most covered tunes in the whole series. Not bad for a handful of 2A03 channels.

Mega Man 2 is a masterclass in 2A03 writing. Two pulse channels, a triangle and noise, and Takashi Tateishi still made Wily Stage 1 sound like a full rock band.

No need to apologise! For a first ever soundtrack that is seriously impressive, writing for the 2A03 teaches you so much about melody under limits. Congrats again!
