My thoughts exactly. It's a temporary switch, not locking, which I suppose is fine for scanned applications (MIDIbox, A6, etc.). The sides are common; input at either "back" pin is connected to both "front" pins, so it's indeed useful for the MIDIbox and you only need use one "side" of the switch. Someone must make buttons for these; I still have some A6 buttons of various colors, and knobs as well, "D" shaft types, so I find that I am going to be producing a MIDIbox with some similarities to the A6, by default! This calls for a particular style of front panel artwork... I've gone ahead and paid out for a SEQV3 setup. Wish me luck and duck, here come the noob questions!!! Waxing selfish aside, I have hundreds of these buttons, and I see that 44+ are standard for the SEQ. I can easily mail something like that out internationally in a standard padded envelope, if anyone is interested. And if anyone knows what similar items cost. I'd like to see, and I'll beat that price.

I guess that a MIDIbox version would not be commercial so it should be okay. I just don't like to step on the toes of another's livelihood. I'd definitely like to see something like this in MIDIbox land.

Today and the next few days are nuts so I can't spend as long as I wish online. I can't find a ruler or measuring tape! This may help; it's 3 perf holes wide (definitely not the 15 or so mm of the one in the above photo!) http://i6.photobucket.com/albums/y222/mpeake/TactSwitch.jpg They have four pins, but I don't know if they're SPST or SPDT (or??) I don't know the part so I can't get a datasheet. Thanks for the replies and the welcomes!

Edit: New and unused 4mm (three perf board hole spacing) quadrature temporary switches, the same kind as in the A6 Andromeda. 12 cents or 0,08 EU each. http://i6.photobucket.com/albums/y222/mpeake/TactSwitch.jpg Either of the pair of input pins are fed through to both output pins when pressed. Let me know if the price is ridiculous in either direction. Know that they are a bit "wobbly" in that the mechanism has a bit of play. Find an A6 and you'll see if you like them or not. I don't know who makes caps for them, but there must be a few types out there somewhere. Back to your original post: Hi, I'm a noob and was once on the A6 Andromeda (Alesis) synth development team. I have some switches that I rescued from the bankruptcy dumpster, and they appear to be usable for MIDIboxes. I'll get a photo uploaded tonight. They're very similar to the brown-cap switch in this pic: http://www.sequentix.com/build/old/images/Switch%20choice.jpg except that they appear to be of higher quality as well as having a blue tip. I don't know if they're worth anything, but if these are useful, I have many and am interested in trades for MIDIbox componentry. Of course, these are likely a penny apiece or something and you only need three for a SEQV3 ;D I'm out for the morning, please let me know if you have any insight...

Brilliant. Thank you for being kind to a noob as well as pulling together the information for the builders who will show up after this. I note from this thread that these displays do indeed work: http://www.midibox.org/forum/index.php/topic,10800.0.html Thank you!!!

Hi, newb question here... The Moog is a beautiful thing; I hope that someone who knows coding might be interested in creating a PIC-based clone. Pretty please? http://algoart.com/tutorials/sequencers/introduction.htm The synthesizers.com 960 clone page offers info on its functionality. I'm not posting a direct link due to this concept being a bit of a conflict of interest with Roger's excellent work. Basically, the Moog acts as a 3x8 sequencer with a built-in clock (a partial 901 oscillator, unstable and drifty with no Tempco compensation). An external gated (sequential) switch allows selection of 1x16 and 1x24 stages. That would be nice to have as an FP switch. The most fun occurs with the "chicken beak" three-position switches, which select Skip, Normal, or Stop for each stage. Skip turns stages off as the unit plays. This is audible in Tangerine Dream's "Phaedra", IIRC, and perhaps Encore (live). The red buttons allow for direct selection of stages to aid setting touchy pitches etc. The oscillator has switched ranges for some reason; this need not be included, and is best excluded to make room for something the Buchla 200 sequencers show to be great fun: a duty cycle control, and a CV in to modulate duty cycle (gate length). You'd definitely want just a touch of noise in the tempo to simulate analog. Would you want to simulate the dips in pitch output occuring from overloaded power supplies? Or the drift in tempo? ;D Synthesizers.com have added a reset to (next stage)= 1 function. Important stuff. Gate bussing would also be fun. I know someone who might be able/interested in making front panels, but I'd have to find out. Regards to the forum and creators! Edit: A random mode would be killer as would analog addressing (if the seq is stopped, a control voltage selects proportional stages. 0v would be stage 1; a maximum determined input voltage (say 10, which is common these days, or 5 which is a vintage standard on the Moog itself) would select the highest stage. It's a vertical progression. It can be used as a threshold detector (stage trigger out) etc.

Hello, I'm also a newb with an LCD question ;D This is a $5.00 backlit 2x40 display, but the driver is a KS0066. I see nothing on that in the docuwiki or the SEQ page, so I'll guess that my enticing, very inexpensive find is not kosher? I know that the above-listed controller is a given, but of course I know nothing about others... http://www.goldmine-elec-products.com/prodinfo.asp?number=G16610 There's a link to a 400K datasheet on it. 14 pin connections plus to power, page nine for input details. Regards to the forum and to the MIDIbox makers!

I almost used ceramics until I saw his rev3 notes (having bought a rev1 board)! Interesting point about them sounding harsher. That could be useful ;D I also wonder why one cap is of a different value. The 2044 datasheet IIRC mentions nothing, and does not display any variance in the depiction of the individual cells the caps connect to. But there it is of course, right there in the datasheet. I don't know if the Mono/Poly, CATSRM and other synths using it followed that advice or not. I sort of figure that you know what you're doing, so keep up the excellent work! It is extremely exciting stuff. Regards, -Mike

Oops, modified my post to reflect that. Sorry. The thing that I am unclear about is the nature of the software that is available for users, and what can be added or changed, and by whom. I'll figure it out ;D

Hallo, I have a Foniktronic SSM2044 board and he's used three 5mm MKS2-type Wima metallized poly caps and one 820pf dipped Silver Mica for the poles: http://www.modular.fonik.de/Page29.html Your choice of caps likely is better-sounding, but I thought I'd chime in regarding the size issue, if that's helpful at all. Great idea, I'd certainly buy a PCB as well! (Edit: Pardon my presumption; I want to help but am simply not very good at doing so!)

Hello Forumites, I'm new here.. The Akai MPD controller is now $200.00 at Zzounds: http://cachepe.zzounds.com/media/quality,85/brand,zzounds/MPD24_fronttop-a2e5f77de08988c94e9b8b40dadb2f26.jpg http://www.zzounds.com/item--AKAMPD24 I'm in love with the MB808 and intend to build one when it comes out again. I also am interested in using it as a set of triggers for my analog modular synth. It would be heaven to combine the MPC USB interface with the Core/etc. and use it to generate at least 8 CVs for volume/velocity, and perhaps another 8 for controllers, to impart MPC style (16 levels, pressure for variable volume press rolls, a real-time/sequenced slider to output a CV to control decay time, perhaps the real-time Erase key) upon the 808 and the modular. (Edit: I know that I'd then need 8 VCAs, but with the quad SSM2164 lurking around, that's not very scary.) I'm a complete newbie to your technology, but sense that this is possible, whether as a stand-alone system or as an addition to the MB808. I would vastly appreciate any insight into making this a reality. Cheers on one of the most exciting systems in years!
