My power supply failed and took the sammichFM out with it. I replaced the rectifier and VREG and am getting proper voltages across the board except some of the digital 5V spots. Mem banks 2 on right all have digi 5v, but the PIC, midi chip, 3 left mem banks, and upper board socket are onpy getting 1.76V. Nothing looks burned and diodes check out. Wondering what could be shorting that line and not affecting the mem banks. Thinking it's either IC caps or a transistor. Any ideas welcome. Gotta bring this back to life. The failed supply spiked voltage up to 15V+

yea i've been checking. oh sweet. I do have access to a mill that uses eagle thankfully. Just looking to revamp my old boards as it's been like 5 years of wear n tear and upgrading housing plus kinda want to make a second one for a friend. There should be a midibox for everyone kickstarter project where we produce more parts than anyone would ever need to make sammiches and midiboxs. Leave no nerd behind.

Looks like the smash TV shop has ramped down inventory and sammich kits are long gone. Anyone know where to get new Midibox SID V2 kits or the successors even or has no one stepped up to sourcing these anymore?

https://soundcloud.com/televicious/b2-1 Can't wait to see what I can do with it once I finish filters for it, but It makes great sounds regardless. This is a recording of it playing in one shot. I sequenced it in renoise and just did a straight recording.

So I had this problem and fixed it with the 1k resistor going from D3 to a 5V+. My midibox was shorting out so I was going through re doing some solder joints including the 1k resistor and now it's back to it's reformatting old self. The Diode appears to be functioning according to my multimeter. It's the Core_R4D board btw. I should also note, it's only formatting Bank G and the Ensembles. usually the ensembles. I got new diodes and resistors for it. If that does the trick I'll be at ease otherwise I'm clueless.

Awesome. Thanks for the reply! At the very least I can use a cheap homemade filter. Break out cabling it is.

Could you use a shruthi filter?

Interesting, the midibox FM did a fine job at making it 6 voices then. Playing with adlib tracker 2 I noticed this MIDI issue with the MPU-401 cable. If i played the notes with a normal computer keyboard It had no problem keeping up, in 18 channel 2 op mode I'm pretty sure i heard every channel. Midi mode was channel to channel. I wonder what they did to make the computer keyboard perfect at polyphony in preview modes.

YES! The only thing I can add is, please make the stereo mixing midi controlled. That 18 channel + optional mixed mode is brilliant. I would love to see that with the AOUT modification. This will make Adlib tracker 2 obsolete to me.

I'd be interested in that CAD file if you still have it. Have access to a laser cutter and lots of C64 cases to work with. :D

woah! :o Awesome project!

Basically, MIOS needs to be rewritten from scratch and the whole user interface will need to be reassigned/redesigned. The source is included with MIOS. Let me know how it turns out! I just went on to working with a SB16 Adlib Tracker 2 and ancient MPU-401, though the Midibox version is still fun to toy with and more portable too.

I've been scouring the internet. I don't think anyone's touched the sega saturn's YMF292 SCSP. The only ways I've found for people to do anything with this chip are mario paint style games or if you buy Sophie (saturn dev kit) from ebay for 600 bucks. Surprised no one's pulled the chip or written a music controller/sequencer program. There was a Japanese game that was basically piano hero that came with a midi interface, but no music creation or sound controls.

well 15 plus drums makes it perfect for midi's 16 channels anyhow right? Have any links to your project?

I just recently discovered trying to control the Audio routing via CC parameters does not function. Is this common for everyone or may it just be Renoise which I'm using to control it with? I've tried the voice CC with no success. I understand the ensemble cc's are only functional with Sysex.
