Dolphinicus Posted October 5, 2006 Report Share Posted October 5, 2006 Hey all. I'm going to be purchaing a MIDIbox SEQ kit in the near future, for building. But - with experience in programming in the Basic language, I would like to purchase a PIC / Basic Stamp, to design and build my own simple Gate Sequencer around - at the same time, learning how to work with these devices.Could anyone out there recommend a unit that I could purchase online, that would allow me to use, for designing / building a Gate Sequencer around?Here's what I'm looking to build:- a Gate Sequencer, that would have between 4 and 16 steps of +5VDC Trigger or Gate output- programmable by up to 16 switches (1 for each step - Gate/Trigger On or Off)- playback of that 4 to 16 step sequence - looping, or 1 time only- Internal or External Clock Sync- an LED for each step- software to be programmable in Basic (preferred) or Assembler (which I would teach myself)- software for the device to be simulatable within the PC, before it's sent to (burned into?) the deviceI have enough knowledge to design / build circuitry for the interface FROM the controller. No troubles there. I would much rather design and build a Gate sequencer around a microcontroller, than with discrete circuitry as I have in the past.I haven't a single CLUE though, as to which controller would be appropriate from Microchip. :( Could anyone recommend a proper unit, that I could go with?If you have any other questions, please ask away - if I haven't been clear enough in what I'm trying to do. :o :)Thanks for any possible help. :)Take care,Warmth and Peace,Rykhttp://www.sdiy.org/damian - my modular synthesizer's homepage Quote Link to comment Share on other sites More sharing options...
audiocommander Posted October 6, 2006 Report Share Posted October 6, 2006 Hey Dolphinicus,I'm not into Gate Sequencers (so I may be missing something elementary here!) but as long as the gate is just a +5V signal with no (or not much) current drawing, I think you could handle this with DOUT modules?In this case, you could build a CORE-Module with a PIC 18F452 (the default one for MIOS), upload MIOS, choose additional I/O modules and start programming your own MIOS-application :)Cheers,MichaelEdit: I would recommend programming in C, which should be a lot easier than learning ASM... and the available application skeletons are very good! I wrote kind of a simulator/debugger for C-based projects (ACSim), not very elegant, but useful... take a look at the Wiki -> Application Development ;) Quote Link to comment Share on other sites More sharing options...
Dolphinicus Posted October 6, 2006 Author Report Share Posted October 6, 2006 Ooo! Thanks muchlee for the suggestion, Audio! :) I DID learn the basics in C++ and was able to crawl around in the code for a little while, understanding where I was going. I'll wander over to the Wiki section that you've mentioned, and if all fits - I'll go that route. (Could fit together better, as I'm going to be ordering a system for CV sequencing anyways - greater chances of their working with each other. :) )Thanks much. :)Edit: Just looking at the modules / etc. listings, at SmashTV's site - (being a complete beginner with this system), do I need to order anything other than, the core kit and DOut kit? I'm placing an order right now (today - before work). :)Or - will the two, allow me to go from the beginning? (I.E. Do I need to order any pots; other modules; MIDI module; etc. to use the unit specifically as a Gate sequencer?)Rykhttp://www.sdiy.org/damian Quote Link to comment Share on other sites More sharing options...
audiocommander Posted October 6, 2006 Report Share Posted October 6, 2006 do I need to order anything other than, the core kit and DOut kit? I'm placing an order right now well, I'd recommend a DIN module, although you can work with MIDI-Messages for Input-Control / DOUT-operations; an LCD is very useful to know what's going on (if you stuff it with an plug, you can re-use it later on). MIDI I/O (one in/ one out) is part of the Core, as are eight AIN-inputs, so no AINx4 needed if 8 pots are sufficient.best regards,Michael Quote Link to comment Share on other sites More sharing options...
Dolphinicus Posted October 6, 2006 Author Report Share Posted October 6, 2006 Right-o and thank you muchlee again! I'm just putting the order through now for:1 x CORE Kit1 x DOut module Kit1 x DIn module kit1 x 20x2LCD2 x 24LC2568 x EncodersThat should get me started. :) If I'm needing more things later, I'll get to ordering them as well. :)I can't WAIT! :DThanks again. :) Quote Link to comment Share on other sites More sharing options...
