How's this for an interface? I've ignored morphing - it only deals with random patch generation. The big dial is used for cycling through patches (eg "SIDPAD", "SIDLEAD" etc). The two buttons are to save the patch or save a copy. The three rotary encoders are for setting restrictions on CC's. The midi channel which the random settings will be sent to are selected via the Midi channel button. This could be moved to be on the LCD and eliminate the need for the LEDS. Finally the big red button to generate the info. That's 11 DINs and 16 DOUTs. Short comings: It doesn't allow for SysEx and I guess that storing names for CC in each patch would take up too much space. I'm sure I've missed something but how's that for a basic interface concept? Obviously it isn't as powerful as a PC based script, but I'm trying to elimate my PC from my music making process. Cheers Benedict

I've been thinking about other ways to impliment this. What about creating another MIOS application to do the job? You could select which midi parameters you wanted random information generated for then hit the big red button. This would then be useful for other synths/midi gear. With an LCD screen and a bank stick to store settings (what midi info to generate) it could prove rather handy. Maybe it could do other stuff too. Patch morphing is the only thing that springs to mind - stick in a bank stick with SID patch on it, select two patch, morph time, then hit the big red button. I don't have any idea how to program this (I know a little VB & pascal - I've never tried assembly or C), but presumable if the PIC didn't have to handle the functions of the SID then it is do able. Any one got any thoughts? Cheers Benedict

Oh well. I didn't know about the pearl script so thanks for that. Shame you can't do it without a PC - I'm trying to get away from my PC for music, (I always end up spending more time messing with the computer instead of making music). Cheers Benedict

LOL. I might try and stick a random button on my sofa and see if I can get a ready made SID! Cheers Benedict

Hello All, I've finally ordered the parts for my SID and I hope to make it over Xmas. Even before I've made it I want to change it! What about a "random" button? When pressed it would come up with random settings for all the parameters. It would be a great source of inspiration! I've had a search on the forum and Wiki for "Random" but I couldn't find anything. Surely other people have thought of this. Is it do-able? Cheers Benedict

Cheers!

Hello, I bought 3 40x2 LCD on ebay for not very much money but I don't know if they're the right ones. As far as I can tell they are the TM402C on from here: http://www.tianma.com/character_displays/index.html Are they any good for use with a SID? If not I'll just have to sell them! Cheers Benedict

Hello all, I've been looking around here for a while and I plan to build a SID (I posted a while ago in the design concept forum), but before I build anything I think I should do a bit of reading up. Can anyone recommend a good book or 2 that will fill me in the on the basics of PIC programming and audio circuits? Are there any other areas where some reading up would be a good idea? Cheers Benedict

Hello all, I came across MIDI Box on the Sound On Sound DIY forum. I'm not entirely new to electronics - I did it at school, but that was six years ago so please excuse me if I ask some stupid questions. I'm really interested in making a SID synth, I want some degree of hands on control so from what I've gathered I need the follow: 1 x Core module 1 x SID module 1 x LCD + 6 (or 10) buttons 1 x DINx4 Is this correct? I'm also confused by the power supply. I presume these will be separate circuits but I can't seem to find any PCBs or schematics for them. Where do I find them? If all goes well and I manage to get the above working I think I'd plan to expand to a multi SID. I see from the pictures that the outputs from multi-SIDs are on 4 separate mono outputs. I've got some questions about this: - Is it possible to incorporate a mixer to mix down the 4 mono outputs to 1 stereo output? - Would it be possible to incorporate pan information within a patch? Would it be possible to assign a LFO to a pan control for each SID? - How is polyphony handled by a multi SID? If all SID modules are linked does this mean you can get 12 part polyphony? Obviously this is just to satisfy my curiosity because I haven't even built my first SID yet! Thanks in advance Benedict
