The SID can do a resonant high-pass filter while the SSM adds an LPF resonant characteristic as well. Like cranking up the resonance on an MS20's two filters, but then being able to move each independently via modulation...should produce some nice sounds, moreso than simply using the SSM to do LPF of the SID oscillators alone... There is much to consider :)

Increased my order size- remembering that SIDs can do resonating HP sweeps- combining an LF HPF resonant sweep with an HF resonant sweep provides two resonances moving independently. There is a lot that can be done with such a configuration... THANKS!

Edit: Every thing is as it should be. Impatience boy sits down and waits for his betters to do what they do...and it is done. Thanks again for everything SID!

If payment is currently being taken, then my second email must have been lost in the ether as well... I'm willing to do what's required to fulfill this, if I'm missing something...

This rocks, thank you so much! Wilba: Per your note in the thread above, I emailed you to confirm my address and order, but haven't received a paypal request for the SIDs yet- I'll take it that you're still gathering data and that I'm not lost in the shuffle, as can happen. Looking forward to it and thank you as well!

I have a number of salvaged mod and pitch wheel assemblies for the Alesis Andromeda - spring-loaded pitch wheel, non-springed mod wheel. I don't remember the pot value, and they're in storage so I can't jump up and find out, but I have them if anyone is interested. I'd certainly sell pairs for less than what is asked for one at that link (although the QS wheels are wider, if you prefer that). PM me if you're interested and I'll reply when I can get at them (going to be a bit of a wait).

Please put me on the waiting list as well, thank you.

You're much further along in your building and applications knowledge of the MIDIbox gear than I am, and you're answering some of my pending questions, so thanks. So far as I can tell, the MIDIbox CV has the eight channels out, and each can be a note plus pitch bender CV, but I can't tell if there are any LFOs involved. It's nice to have a freerun LFO available, summed into the note(s), and to use pressure or the mod wheel to perform its amount. I know that you could patch that up...but the MIDIbox SID with AOUT comes close to being ideal for this, if you only need two "note" channels. I can't tell from the data if the matrix allows for pressure or the mod wheel to control the amount of an LFO to any of the CV outs (or if velocity can be used to dynamically modulate envelope amount to a CV out), which would make them extremely attractive to me (I'd use one env hardwired to a VCA to shape the output of the 6581 self-noise). And to use in the analog modular as well. So many MIDIboxes!! So little time!! So close to ideal!! I do have one idea- you could use a 25-pin (or more) connector at the back of your SEQ to connect to the trigger ins on your drum modules. Easy connect/disconnect.

Wouldn't you get better timing by avoiding MIDI completely and using your SEQ for the Gate or multiple Trig outputs? That's my plan. MIDI, in theory, even in these excellent projects, is still serial, right? BTW, I've been unable to find which PIC the MIDIbox CV uses- I'll take it that it's a 452? Yes, I've searched and I've gone over the ucapps and WIKI pages- is it in there somewhere? The answers I need seem to appear on those pages after I ask them, somehow ;D Great setup creatorlars, I'm after the exact same sort of thing.

Congratulations on discovering the hidden MIDIbox Bagpipe OS! Seriously, I'm sorry and hope that it works out easily and quickly.

Truly exceptional- thank you for documenting and sharing your work.

Thank you! Mods: Should I delete this post to increase the SNR? Ordered prior to seeing the Ultracore. If you have a SEQ to which you'd like to add channels... Same price as Smash, of course, $14.00 for the IIC complete kit, $5.00 for the IIC PCB. The PCBs are shrink-wrapped together; I won't separate them until I have a first order for one or both. Also one "large" stripboard, $2.50, unopened. I accept paypal but add the 3% transfer fee. Shipping extra, shouldn't be very much, a few dollars. Thanks for looking. I could use a couple more bankstick 512s if anyone wants a partial trade.

I for one would not buy SIDs from a person in that outfit. Well, maybe I would because I want some SIDs...supply and demand. Sigh.

You're waiting to buy/build a 6582 PCB set, right? http://www.midibox.org/dokuwiki/wilba_mb_6582_base_pcb_construction_guide?s=power+supply+option (I'd ask after a couple of tested 6581s...)

Pardon me- there were several assumptions in my post and it's your thread/project. I was just attempting, in my ham-handed manner, to reinforce your own post regarding Mouser parts. I look forward to the PCBs!

Yes, Mouser BOMs should likely reflect Smash's parts lists: http://www.avishowtech.com/mbhp/mbhp_coreR4d.html

Seeing on mikesarcade.com that Pokey is the sound chip on my old favorite, Tempest, I bought a pair of sealed BallBlazer carts through eBay for about $15.00, still a touch less overall than ordering from Mike's, etc. Well...they're soldered in! Not too surprising as they were after durability... My good advice is to just order from Mike's or similar and get them loose, NOS... I can't wait to add that classic "MONG" tone to my rig ;D "Somebody get this duck away from me!" -Strongbad

Thanks!

I was hoping that someone might have schemos or links to the originals. Can't build without those...or perhaps if someone has already offered this in a hardware solution, a link...looks like something that one would indeed have to build one's self...the MPC 60 doesn't sound as good as the original two Linns. Depending upon your needs; the early ones had little rolloff and were bright. The early 9000 and MPC had lots of rolloff and mix quite easily as a result (plenty of room for vocal siblance, filter sweeps, etc.)

Thank you for your fast reply, but neither of those behaviours are what I am after...I'm looking to hear two SID chips at once, played by the same track or controller, with each producing an entirely different sound, and to edit the two patches into a more interesting whole (two filters at once, for example. Basic "Ah" sounds can be created with two resonant lowpass at once, or a resonant LP plus a BP. Contrary motion in resonant peaks is wonderful as well, much less what can be done with different oscillator tunings per chip, etc. Yamaha FM pianos were often done using two carriers at different pitches, one for the piano body and one for the tine.). If the engine does not allow for two sounds/chips to respond simultaneously to a single input, it would preclude live playing, but would allow for the user to copy sequencer tracks to adjacent MIDI channels...

Sorry to post here, I thought it better than to start a thread.. I've searched and read and read, and am not clear if two SID playing different sounds can be set to the same MIDI channel in an Ensemble (and the user edit the two sounds independently via FP and MIDI). The User Manual implies that multiple sounds can be zoned on a keyboard on a single MIDI channel, and that different SIDs/sound can be of course set on different MIDI channels. I'm into using voice pairs to create single sounds of greater complexity...and will the 6582 allow a four-voice mode where two sounds may be layered/edited/played via one keyboard/MIDI channel? I assume from the MIDI channel selection note in the Bassline manual that it can, but assumption has bitten me on the ass many times. Thanks for an incredible set of projects and initiatives.

For reference, and I'll be moving along now that I've forced my opinion upon you all-- In the Andromeda, we used four Burr Brown PCM54HP through-hole DIPs. They're $19.00 each at digikey, and can obviously be used in parallel. Just tossing around some options in case anything sounds interesting.

The 16-bit AD669AN IC used in the Expressionist is still available from Digikey for 16EU (but you have to buy 13 minimum). This is better than Farnell's 19EU price at 100 quantity. The only slight problem is that the Note outputs are buffered with LF353s, and there is some kind of transistor buffering each Gate output (all are SMD but the AD chip is through-hole. Voltage distribution may be being accomplished with 4051s. There are likely reasons that this chip wasn't your choice for a simple CV solution :) Edit: AOUT_NG is also obviously output buffered.

Ho yes, they're verah nice-ah! Now go a way or I shall taunt you a second time-ah! (Waiting for the board, for my two 2044s.)

;D ;D ;D ;D Edit: When do we begin calling them complete songs and not demos? Great stuff!!
