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. Channel logs: https://freenode.irclog.whitequark.org/~h~yamahasynths

I won't need it, but thanks
<andlabs>
I do have a Roland Boutique D-05, which is the newest LA synthesis thingy that Roland made
<andlabs>
one day i will try to see if I can make it usable from dosbox as an MT-32

ej5: Why is there a need for backup power? And while that is indeed a cute BFC, why not use a battery?
<ej5>
don't like dealing with batteries soldered on a board
<cr1901_modern>
ahhh fair. There's plenty of good reasons to feel that way
<cr1901_modern>
I actually like barrell NiMH batteries when they don't leak
<cr1901_modern>
uhhh, NiMH is the wrong chemistry
<ej5>
true story: swapped a nicd barrel battery out of my trs-80 model 100 with an nimh. after a few years it too leaked :(
<cr1901_modern>
:(... one of the rechargeable chemistries is objectively better than the others but requires a microcontroller to prevent it from blowing up

this post claims timidity has support for the recomposer file formats
<cr1901_modern>
Not to derail the topic, but does anyone have official docs for SM8521? Sharp still has a datasheet on their website but no opcodes
<cr1901_modern>
And looks like MAME project figured out the opcodes from REing (fun)
<superctr>
if there is an MAME implementation and were official docs, Stilett0-away would have it

Pietro Gagliardi, [22.09.19 15:55] well I spent all day so far trying to revers eengineer the sequential musicmate software disc so I guess I can add C64 to the list of platforms I've done disassemblies of code for
<andlabs>
Pietro Gagliardi, [22.09.19 15:55] made very little progress on the communications protocol though
<andlabs>
Pietro Gagliardi, [22.09.19 15:55] I think it's using that joystick simulating a kebyoard thing

update
<andlabs>
just confirmed: the D-05 does come with all the expansion card sounds built-in
<andlabs>
as patch bank P3-P6
<andlabs>
music composition update: the midiplus tbox 2x2 works fine, but all the linux software I tried either does not want me to make midi connections, does not record midi notes for some reason, does not fit in a 1024x681 screen (rosegarden), or has hella lag and stuck note syndrome (MusE)
<andlabs>
ardour on mac just crashes.
<andlabs>
more software attempts will have to wait for next week
<andlabs>
oh yeah I alos tried Haiku but I think VMware glithced out and made it stop recognizing usb devices but meh
<cr1901_modern>
>ardour on mac just crashes.
<cr1901_modern>
Well damn
<andlabs>
okay I think I figured out the protocol for that sequential keyboard! just need one of my own to test it with...
