Nice track and the MB-TIA it is quite rich indeed :) I'm interested, my Poly-800 II died years ago, a lot of corrosion, not sure if I'll ever be able to do anything about it.

...I love them drums ;)

I didn't realize sooner things were moving, no problem for me too.

Thanks :)

Good :) Once I was able to achieve something similar to what you are asking. There was a mod around for Cadaver's GoatTracker that implied a .dll file, a real C64 and a DIY cable. Parallel port of the PC <=> user port C64, I'm not sure, it was quite some time ago, but I do remember that worked only in a DOS environment to me so I had to use a Win98 PC. I don't remember the protocol involved but the speed of the communication was similar or slightly faster to that of MIDI, you basically had to restrain yourself to 1X SID. Let us know if you find something, it's interesting.

Looks like it was working then ?

Very nice, I'd love to play with one so signed myself for the bulk order. Cheers Luca

Latigid, thanks for the docu... and for the PCB of course ;)

Hi. Didn't try it but the player you'll find here should do: https://www.elektron.se/support/?connection=x-sidstation#downloads. It uses the ASID protocol which is supported by the MBSID.

Hello, I've added myself to the list. Hope is OK.

Yeah, very nice job you've done :)

Received mines, nice :) Thanks Jerome

E vai! :smile: Non era facile da scovare, ottimo lavoro. Per quanto riguarda il controller non ti posso aiutare, non ne ho mai fatti. Buon anno

Mi dispiace, non ti buttare giu' pero'. Qualche anno fa in tre, ciascuno per proprio conto, ci siamo messi a costruire il MBsid. Gli altri due provarono la strada del DIY anche per le schede, io preferii comprarle direttamente. Uno si fece il core con il bromografo l'altro addirittura a mano con una perforata, abbiamo faticato tutti e tre ma per me fu piu' facile soprattutto in fase di troubleshooting. Dopo vari tentativi e molta pazienza funziono' tutto. Quasi tutto, apprendo ora che la versione "perforata" del core e' stata buttata via.. Ciao

Humm... supponendo che la configurazione computer drivers riguardo il midi sia testata e che sia su Win, che ti dice MIDIOX quando connetti il core? Per capire se il microcontrollore effettivamente parte direi di ridurre le possibili variabili al minimo. Quindi prendendo in considerazione solo il midi out del core possiamo del tutto escludere il fotoaccoppiatore (6n138) IC2, magari levarlo momentaneamente dalla scheda. Per partire il PIC non ha bisogno di molto credo, un voltaggio positivo su MCLR(1), l'alimentazione Vdd (11,32) Vss (12,31) che hai gia' verificato, il cristallo Q1 e relativi condensatori C1, C2. Il MIDI Out e' facile, R7 con TX, massa, R8 con +5V, occhio a non aver invertito i pin sul DIN 5, mi e' capitato spesso, se non funziona prova a scambiarli (massa sempre al centro). In questa situazione tutto il resto del circuito dovrebbe essere superfluo ma va controllato non ci siano corti che potrebbero impedire il boot del PIC. Facci sapere :) Edit: testa tutto con MIDI-OX Edit 2: Ho trovato una prova piu'veloce e sicura: Accendendosi il core dovrebbe mandare una richiesta di upload che fa tremolare il LED.

Ok, hai controllato i voltaggi sulla scheda? IC1:MCLR(1) - IC1:Vss(12) = 5V IC1:Vdd(11) - IC1:Vss(12) = 5V IC1:Vdd(32) - IC1:Vss(31) = 5V IC2(8) - IC2:(5) = 5V Un altra domanda, che computer ed interfaccia midi stai usando?

Ciao Non conosco il pickit 3, c'e' un sistema per verificare la corretta programmazione del chip? In altre parole ti ripeto il consiglio di cimo, accertarsi prima del bootloader poi hardware troubleshooting.

Thank you, TK. :)

Sparx, sounds like a sweet plan :) Re-reading the entire thread from the player perspective: lyrics, tempo and key changes, a loop function, a filter/routing function, I see a lot of possibilities. From a first, yet functional and small midi player (Core, LCD, SD Card, SCS) with lyrics, tempo and transpose functions. Toward even more hypothetical (not being a programmer I can only suppose :sad: ) advanced configurations where for example with a button matrix it would be possible to recall snapshots of different settings of more advanced functions like loop points and routing. ..now you can definitely shoot me :whistle:

Sparx, four independent outs? Yes of course. Pete, you're a nice guy :)

Thank you TK for your clarification and willingness to help, I had this doubt/hope the possibility was already there. Pete I'm sorry but my question wasn't really related to yours, just another one. Does this multiple outs thing belongs to Midio128? I don't know, maybe not, but I chimed in believing to have similar needs to the OP ones, an affordable, small midi player with multiple outs. I'm curious, what's your opinion about lyrics output, it belongs? I like MIDIBOX also for his modularity which means to me, in a broader sense, freedom, choice and "something which matches the needs of multiple users". Agree, with choices could come complexity but maybe your firm "NO" was a little bit drastic in this context. Or maybe yes you're right, a full fledged midi file player doesn't belong at all and, I'd like to add, is the kind of application that deserve a dedicated hardware project, another smaller MBSEQ variant. TK, Pete don't shoot me :whistle:, just a thought. Peace and love :)

Hi I'm going to ask about this: "..multiple tracks can be played in parallel." Obviously with the MBSEQ I can have different tracks outputted to different ports, but is this feature extended to the midi file player? For example, is it possible to route different midi channels of the midi file to different output ports? Or maybe there is another way to do it? Most of midi file players out there have only one independent midi output port, The MIDIBOX platform up to twelve (!?), great stuff :)

And two for me, cheers :)

Got mine Saturday, thanks TK!
