i have one of these xr-2206 chips sitting here, i was wondering this very same thing... can we hook one up to a midibox core and build some synth software for it? (or should i build the function generator i had planned on building with it?) hmmmm....

a Hot Glue Gun!

here is a soundbyte from the drum engine and internal sequencer. NOTE: this is the first time i ever touched it ;) enjoy! --JMS Untitled (2).mp3

here's the story so far: i ordered some parts a couple weeks ago from a nice little web shop and soldered them together. i de-soldered ever so patiently as to not burn up, a sid from a c64 i've been sitting on for about 3 years. the c64 was bought on ebay for like $15 us including shipping. the in-progress synth has 1 6581 sid that was manufactured in the 51'st week of 1983. it's at the stage where i can play, switch and edit patches. i need to build one single power supply for the unit, make some panels for the empty holes in the case and be done with it!! from the c64 of course i re-used the sid. i also reused the power jack and some other port on the back for my midi in/out sockets! i'm still pondering using the power supply parts of the c64 mainboard as a decent power board for the synth or just building one with all new parts. thanks TK and midibox crew for the nice project docs! pics attached, when i get the inside wiring done i'll post more!

thanks for posting the pics! i always enjoy peeking inside machines like this... it looks kind of similar to the s2000 (the only hardware sampler i've opened up) which had to be torn apart and the floppy drive replaced before it was even usable... geez!

prototype datawheel picture before it was all mounted in the box... scroll wheel and the encoder from an old mouse i had laying around, the encoder acts as a hub on one side, a small LED acts as the hub on the other side which in turn is able to light the whole deal up... i mounted a switch that was salvaged from the same mouse under the LED "hub" which is mounted in a way to allow it to travel enough to trigger the switch without breaking the legs after repeated use. it's working awesome! as far as looks go, remember i said PROTOTYPE in the first sentence of this post! mouse parts, super glue and bits of plastic = encoder/datawheel!

mmmmm'kay... i've now at this point used BOTH Millennium AND Mesa II... i'm pretty sure they are VERY CLOSELY related... i'm thinking maybe Akai bought thr rights to Millenium or something and called it MESA II. i've never used MESA I, so i can't comment on that. while playing around with both software packages... i have determined MESA II to be a more rounded (less buggy) tool. therefore i am going to strongly disagree and reccomend anyone who is using or going to be using an akai s2000 hardware sampler use MESA II instead! NOW... back to my sequencer project... this thing will let me program in a song like a1->a2, a2->a3, a3->a1... everything is fine until i hit PLAY and then it reboots everytime. (i tried 352 times, lol) what am i doing wrong? i can't figure it out... the rest of the functions on this box work flawless so i'm pretty sure i got it all wired and programmed correctly. thanks for reading this... and thanks ahead of time for any advice on what may be the cause of my reboots...

i'd be intrested in one of these pcb's or kits if you have any around.. i just got a unmodded c64 that's just waiting to be a sid donor... EDIT: it's been a while.... oh! ?

lol...

i'm a self titled computer technician, fixing or building computers for anyone that's willing to pay me and maybe a charity case here and there. (with some actual training in electronics engineering at vocational school) hmm... as far as my current day job i started out as a machinist, building dies to stamp things out of steel with huge presses.... then i ended up doing packing, invoicing and shipping awesome car parts all over the world with the same company. i still get to get my hands dirty in the shop when i get bored of the office, oh, i get to run parts between different tool shops around town and check out all the huge machines in other peoples shops. in the past i've delivered pizzas, made pizzas, been a short order cook, washed dishes at a few bars, ran huge cnc machines making parts for who knows what, assisted in the assembly of huge robot cells for delphi/honda/GM/toyota (subcontract of course), i've even worked at mcdonalds a couple different times. in my spare time i like to take long walks on the beach and build midiboxes! ADDED LATER: Those speakers up there look loud!

word. i got the scsi card and mesa installed though i have no cable yet, i'm half tempted to look up the pinout and make my own. believe it or not, i don't think the midi sample transfer is all that bad, but, editing keyzones is a bit tedious on the front panel. the s2000 has an awesome two part datawheel to make up for it. ;) i was thinking of contacting the name of jsynthlib. is he a midiboxer? because that program looks very slick... and i don't know how easy or hard it would be to add the s2000... i do appreciate any tips on the both of them (s2000 and seq2.4) thanks!

i'd rip the electronics out of the plotter, hook up your own motor drivers and a build a z-axis and mount a dremel on it then run it all with emc2 from linuxcnc.org

the s2000 got here this morning... i brought it home at lunchtime and plugged it in... NO LUCK! i had to rip it apart and replace the 3.5 floppy drive before i could even use it including extending the power cable by two inches to reach the new drives power plug (standard pc floppy drive, FYI) after all that i had to spend about 3 hours figuring out hot to get samples onto it through midi, then saving them to disk. (TIP, for anyone else: use "Wav_Akai"). then i spent another two hours figuring out how to assign each sample to a keyzone. (getting close!) so now we have an 808 drumkit saved to the floppy, a kick, snare and hit-hat are mapped to C_2, C#2 and D_2... and we have liftoff! the seqv2.4 is running a 16 step pattern and sequencing the sounds of the s2000! w00t! now... how does the song mode work on this old seq? or how do i chain 4 - 16 step patterns together?

i'm pretty sure bunsen said he already bid.... a couple posts above... (page 19 of this thread)

for drilling component holes use a .030" or if your part requires it .062" drill bits.... tiny stuff. run both the endmill and drill bit as fast as the machine spindle will go without exploding. no joke... i've been running cnc machines professionally for about 12 years, the one in my basement (the one you see in the video above) is just a toy to hone my g-code skills when i am bored!

1/8" (.125") diameter 45 or 60 degree v cutters... it's just a hardened drill rod (or carbide bit) with EXACTLY half the tip ground away after you have ground it to a point at the included 45 or 60 angle. you only need to mill about .005" or .010 deep, make sure your PCB is REALLY FLAT or bits will start breaking.

word, i'd love to play this on my seq during breaks from rockin out on the sampler! (it has a 16x2 lcd?)

heck yeah, so far the code is exactly the same except for the setup.asm and the makefile.orig i swapped up the shift registers, moved pins i don't need to an imaginary SR, set-up the datawheel#0 on pins 3,4 and added my custom setup.asm to the makefile so it would still build the rest, should i need them someday. attached is the two files, drop them in the seqv2.4(e?) dir, remove the ".txt" from the end or makefile.orig and make! EDIT: it's not finished, i need to add the 5th DIN for 3 layers... and 4 tracks, realized i DO need at least those. Makefile.orig.txt setup_mbseq_chr0n1c.asm Makefile.orig.txt setup_mbseq_chr0n1c.asm

hey if you bid on them, just pay for it... and give him my shipping address (which i can give to you if needed). i can send them via US Postal Service i guess...(or fedex or ups if you wish to pay for such), in tiny packages... paypal is cool, they can sit here until people get me money for shipping, as i hand out the quotes. one thing i would ask... NO complaining about shipping costs, as i will naturally find and use the cheapest route to you before i give you a shipping cost. I don't really think i want to be held responsible for the condition they arrive to me in, i won't test them, i won't touch them other than to split them up. sound fair? -- 1. PAY BUNSEN FOR THE SCREENS YOU WANT... -- 2. EMAIL ME YOUR SHIPPING ADDRESS AND WAIT FOR A PAYPAL MONEY REQUEST FOR SHIPPING... if you want insurance on them, tell me that before i do a shipping quote... and what value you would like it to be for (this will also be the customs value, keep that in mind) -- 3. I'll SHIP THEM ALL OUT ASAP one set at a time as the paypals come in. i've got a buncha free boxes from the post office here already, and plenty of spare cardboard to hopefully get them there safe. my email is available, you should know where to find it ;)

Awesome! i'm taking that as a compliment... ghetto and the madmax are both positive in my book! I answered all my questions from above by looking through the code with determination to make this thing work the way i want it to. -- NO! i don't need any pots! (sweet, i'll use the AINx4 ala proto-board that i built for another project) It has 7 buttons(possibility of 8, one is not connected), plus 16 GP buttons and 1 data wheel (via an old mouse scroll wheel and encoder contraption i rigged up). There is also a 16x2 LCD, MIDI-IN, MIDI OUT... everything i need to sequence the akai s2000!!!! with a combination of the scroll/data wheel and the 16 GP buttons i can edit all notes and values... as soon as i add a DINx1 to my dinx4 proto- board to add buttons for the layers... plus 4 extra, to be used some other time. eventually i think DOUTS will be installed so i can see what's going on... until then it's fine to look through the different display screens to find what's going on inside. i'll be taking more pics once i get it all cleaned up and more presentable, it is truly in a mad-max state as it stands right now, lol. thanks to everyone again who helped with info and tips to get me to this point!
