MIDIbox FM V1.0

T.K · February 13, 2005, 3:01pm

I’ve finally released MIDIbox FM - a FM synthesizer based on the famous Yamaha OPL3 chip

6 four-operator voices, 12 additional LFOs, 4 additional EGs, 4 wavetable sequences, 5 percussion instruments plus a complete control surface with 2x40 LCD, 5 rotary encoders, 24 buttons, 34 LEDs are handled by a single PIC18F452!

;D, with each new mp3 of the mbfm i’m more amazed!

the sound of this beautiful synth is perfect for the music i’m into, and together with the mbsid i’ve made, there are a lot of new possibilities for me in making sound/music. Thanks TK!

Can’t comment on this one. Moebius said it all

Thanks, TK

Great work T! - looking n sounding mighty mighty…

Hi Thorsten,

demo 6 is hot, especially the second half! Brilliant what you got out of these three tiny Yamaha chips! Other synth freaks need a big rack synth to get this sound…

Cheers,

Skunk

Congrats on hitting the v1.0, TK! Those new samples really go to show the amazing power of the OPL3 - who knew that chip could actually make some cool sounds when programmed properly.

I hope that in a month or three SmashTV will have an MBHP_OPL3 kit ready. By that time I might actually be finished with wedding plans (ARGH!) and unpacking (STILL!) from the move, and I’ll finally have time to finish off my SID and build one.

Twin-X · February 15, 2005, 6:28pm

Jiles the sounds are just amazing. I can’t wait to get my hands on this synth!.

Thumbs up TK! ;D

T.K · February 15, 2005, 10:03pm

Thank you!

Best Regards, Thorsten.

Great work, Thorsten! ;D

And just in time the new MidiBox Patch Manager 0.7 with support for MidiBox SID and FM is available, too.

INCREADIBLE !

Knew these chips were good back in the mid ninetys; though this is sounding way better than i rember …good one TK !

Finally placed a order in for some pcbs for midibox seq v2, 4x mbsid, & the mbfm

…got all the other parts (except encoders).

Jus kept on putting off getting the PCB processing bits for an eternity…

So keep a eye about - i’ll have somthing to show soon for all the banter

If there’s another order going in for these chips - i’ll probably want to grab a bunch; to save looking around for yet more old soundcards…

Just got some more old soundcards..

One Aztech card did not have a YAC512 but a LS-215 412GH.

I think this is also a DAC, but there are no datasheets.

Will check pin connections to the YMF..

Well, I’ll post this here this time instead of spamming TK’s mail

I did happen to find one more card that no one seems to have listed yet: Creative’s Vibra 16 (code CT2260). And it includes both the DAC and FM chip, one of each o’course.

Regards, Petri

Edit: I still seem not to be able to spell properly :-[

T.K · April 14, 2005, 7:37pm

thank you! I’ve added this card to the list

Best Regards, Thorsten.

Hi, any news on this?

I found the Ls-215 on a Mediamagic ISP-16.

hi there,

found some more sources for the yfm/yac couple:

Soundblaster vibra16 / CT2810
Soundblaster vibra16 sPnP / CT2890

both ISA

and

the onboard sound of some stone-age siemens socket5 motherboard with intel FX66 chipset; out of a siemens Pentium120 workstation

It’s too late to determine the PC type now, sorry…

regards kc

T.K · June 25, 2005, 5:07pm

thanks kc, I’ve added the two cards to the list (I haven’t added the motherboard to avoid confusion…)

Best Regards, Thorsten.

What about MIDIbox FM 2.0 with OPL4? Since OPL4 has all OPL3 “inside”, it’s like having OPL3 with extra stuff (wavetable and all that…)
