I agree it seems that a module could be made to plug the BC into an AIN module, using the top part of the 1st schematic... Gabz, do you understand that schematic? I have a very basic understanding, but not so full as I would like it to be... More study required from me. I have just posted to the yahoo group, hopefully the moderator will approve my message for posting (yes, they moderate every single post!) and we'll get some info soon.

I was thinking earlier that a S&H circuit might help ... But if I were you, I'd take TK's advice. He knows stuff ;D

I've heard this too (can't remember where)... You make a good point, but if there's an LCD on there, I'd say that would be sufficient load.

Right you are :) The change in direction of current flow creates electromagnetic interference which can flow into the data lines and make false 1's and 0's. This, I am sure of... But DC, I don't know about? This is the part where the IT guy (me) asks for advice from someone with more of a clue about electronics :) heheh

Thanks TK :) I always love reading your comments on the inner workings of MIOS. It really is an impressive work of art :)

Something just occurred to me... Power and data signals mixed together in the same cable... I mean, obviously it works OK in the ZTar, but even a total electronics n00b like me knows that it's not recommended. (OK I know about this from my IT work. Put CAT6 next to power = network issues) I wonder if there is some kind of special circuitry in a Ztar which attempts to overcome the potential for signal noise? Does it come with it's own MIDI cable? Maybe it's internally shielded?

I dunno, I really liked the look of those buttons below the screen. They give it a nice sense of depth, the way they spread out like that... Although I did also think to myself that they might cause confusion seeing as they aren't lined up with the areas on the LCD where the related values would be displayed... Looks vs functionality.... I guess it's a personal thing... Me, I couldn't decide ;)

This is exactly why I added a digital camera to my toolkit on the wiki last night. It might not get as much use as your soldering iron but it's sure useful when troubleshooting gets tricky... And of course you can post images when you're finished, to show off ;)

Yeh well it's a combination of the signal dropping out when the contacts in the fader lose contact and then arcing as they come back in contact with each other.... They get worse with age because of oxidation (rust) and dust/sweat/beer/weed/fragments of groupie's underwear messing up the contacts, hence making these disconnections and reconnections happen more and more often... If it's durabiliy you want, you can't go past optical faders, at least electronically speaking... Of course the mechanics of it will vary... Yeh all my DJ buddies learned on substandard gear - I think it forces you to have a greater skill - Clearly it has done in your case. Flashback: All my DJ mates started out when we were about 14, we all pitched in to put together the $20 needed buy two crappy 2nd hand belt-drive decks from our local dodgy pawn shop. You can imagine the quality of a 10 dollar turntable ;) My good mate Flownez (who is a member of this board - I miss ya mate!) used his electronics skills to wire in some rotary pots which I believe he stole from his alarm clock (imagine what your parents would say) which acted as a pitch control. They mixed hiphop and 200BPM jungle on that crap... If that doesn't force you to develop mad skills... nothing will! :D Of course, no matter how skillful, there're some decks you just can't scratch on! ;D

Derrrrr! That's oct++, not oct-- ,etc... Helps if I read it properly ;) hehehehe Geez I sometimes wonder if I should try learning more C to write my seq or just stick with ASM. I don't know... I just find ASM more easy simple and straightforward... Am I weird? Does anyone else prefer ASM over C? (For reasons other than code size and execution speed)

I'm not that excited really, I don't have much use for a breath controller, just trying to be helpful :) Did you test for reistance and capacitance and voltage? Obviously you'd have to power the thing up first, seeing as the innards may not work without being powered, you might have to open the case so that you can get at the connectors while it's all plugged in and working...

I'd be interested to see the performance comparison between the looped statements you guys have written, the divide operation (which can be done in pure ASM by the way) and a table lookup... Obviously the loop/while way of doing this will vary depending on which note is being calculated... Higher notes will have to be subtracted from less times, meaning less loops. I was also thinking of ways of optimising the function like subtracting in 2 or 3-octave steps, but i imagine that in a range of only 127 that would be overkill and would introduce more overhead than it would save....

That's clever! Not meaning to hijack the thread, but as a long-time guitar player I'd love to help with that if you like Wilba. I'll drop you an email about it so we can keep this thread on topic ;)

Zoner Draw is very good... As Wilba is aware I've been toying with it too (I Promise I'll reply soon Wilba :) ) and it comes highly recommended...It is very cheap too, I hadn't looked into how much it would cost to buy. Free would be better.... But in the meantime, it's Zoner ....

Just PM me and tell me what to do... I'm good at following orders ;)

Nice one mate, thanks for sharing!

A lesson for us all :)

Sorry I 'jumped the gun' there mate... I use babelfish to look at some french and german language posts so that I can keep in touch with my brethren in other nations :)

Moxi maybe if you start this I can assist you :) I don't have a lot of time, but I'm sure I can find some time somewhere...

Now I almost wish I lived in France :)

I'd sure like an english version, but I wouldn't expect someone to do all that work for me.

Thanks for the info TK :) I'll start from the C skeleton and go from there. I'm sure it will be difficult to build from scratch without using any of your existing code, but I'm also sure that I will enjoy the challenge ;) I wonder if you could tell me if there are there any kinds of functions which do not perform so well in C, which should be done in ASM instead? I was thinking that maybe mathematical functions like divides would be faster in ASM....

Hi TK, I notice that you are putting a great deal of effort into the C functions in MIOS... Is the intention that one day you will phase out ASM based applications? Or is the C code only for ease of use in those occasions where optimised code is not so necessary? The reason that I ask, is that very soon I will begin code work on my sequencer, and I am wondering whether maybe I should do it in C instead of ASM, in order to comply with your plans for the future, or if I should continue to write the code in ASM.... Either way I am happy... Writing in C will make a port to Atari ST easier, writing in ASM will mean smaller (and possibly faster?) code :) Danke!

Hey Artesia, I do like that layout but I understand your idea to encourage people to make their own faceplate designs.... A subject I've wondered about quite frequently lately is what software to use for the faceplate designs. Obviously there is Schaeffer's FPD, but it's not so simple to use and not so graphical, so it doesn't really give you a good idea of what it will look like in the end... For example you can put the holes for the Perhaps someone could suggest a freeware/open source application that would be good for this kind of work? Obviously it would be best if it could export files in some kind of standard format, so that those of us which have access to professional software can still use the files.

A Korg WaveStation A/D can do that too if you have the RAM expansion :) I suspect the other WaveStations may do it too but mine's an A/D..
