ChanServ changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic.

<andlabs> okay yeah cowgol's tooling is too linux specific to build right now
<andlabs> the test suite relies on linux
<andlabs> blah

<cr1901_modern> My brain keeps seeing "Cowgol" as "Caldor", which is something _maybe_ 3 people in this room besides me know what that is

<andlabs> also have something very cursed https://bitbucket.org/rhinoid/asm68000experiment/src/master/
<cr1901_modern> Idk the answer to your question, but I think I'm gonna need an exorcist after seeing that bitbucket link

<mrspicy224489> This is what edward-d tech says about GEW12: "Conceptual, technical and spritual successor to the horrid GEW7S. However how it is much better, with 2Mbyte address space (instead of 512k in GEW7) but still in 8kbyte pages for control cpu (that still has 64k address space), and it has built in MIDI UART. Still sound is abominable, partly due to
<mrspicy224489> intentionally lowpassed/crippled samples (even when not saving space: like for the crash cymbal and certain strings - just severely lowpassed but still taking as much space as a fullband sample).
<mrspicy224489> mostly used for pseudo-stereo sounds and dual patches, so that synths are 16 voice. No effects. Sample formats supported are 8bit signed and packed 10bit.
<mrspicy224489> 76-key digital piano YPR-50, along with just a 1Mbyte rom for everything"
<cr1901_modern> Wonder how much a broken GEW12 keyboard would cost so one could extract the chip
<mrspicy224489> The ROM? I've done that, but I haven't dumped it
<cr1901_modern> mrspicy224489: Well, yes. But I was more thinking desoldering it and putting it on a breakout board so one could play with feeding it signals
<cr1901_modern> Do you have pics of your setup?
<mrspicy224489> I don't have an arduino
<cr1901_modern> breakout board is a generic term
<mrspicy224489> Or breadboard
<mrspicy224489> But the arduino would be hooked up to the breadboard
<cr1901_modern> And you solder wires to the GEW12 (it's a surface-mount part, correct?)?
<mrspicy224489> Not to the GEW12, but to the ROM
<mrspicy224489> And yes, GEW12 is an SMD part
<cr1901_modern> ooooh, I thought the GEW12 had the ROM embedded inside (and there was a debug interface to read it out)
<mrspicy224489> That's the SWL01. The SWL series SoC's have a JTAG port
