  1. So modular synth heaven is getting a big step closer. Congrats :-)
  2. Thanks, all of you :flowers: Regarding moar SIDs, I´d prolly go the same route as Antix and opt for a few moar 6581 noise monsters, but no hurries and not before MBSID V3 :) Greets! Peter
  3. SID happens :)

      heheh, thanks a lot :-) J, you will love the sound and no mood lights for me :-) - Antix, the acrylic frame is still missing, but i got used to the blueish VFD (which is glass and close to the panel) - it looks quite retro in red/blue :-).

      I really really like your rig :). Looks really much like how my studio is gonna look like when I move house :D

      Well, thanks! :) Have fun building it (having a seq close to a keyboard is really recommended :-))

  4. This track almost exclusively features the MB6582 (only a machinedrum for percussion and a piano patch for a bit of "classic" touch were added, the rest is 100% SID... Live sequenced with the ever-stronger MBSEQ (used the improved poly rec mode for the piano). ... need ... moar ... sids ... :-) Greets! Peter
  5. Hi Clemens, Respekt! Time Warp ist absolut super! Respect! Time Warp is incredible! Greets, Peter
  6. Hi ultra, Dimension-wise, it is more like a 4x20, i put it in the MB6582 just to hypothetically test if it would fit for MBSID V3 :whistle: http://img4.imageshack.us/img4/2223/256x64inmb6582.jpg Regarding the font... no codez ready right now to render them, but it will happen at some point in time :) If you have a look at the Dave Smith "Tempest" videos, you can get a glimpse of how fine this thing looks :-) Greets, Peter
  7. All four requests?!? :frantics: TK., did anybody tell you lately, that you are incredible? :flowers: Greets! Peter
  8. Ireland, so you could always ask Smithy for component sources :-) No, y-connections are not bad (are even necessary when starwiring), just to some people "busses" may seem more elegant. Greets and have a good time! Peter
  9. Small addendum... TK. suggests "star wiring" for the power supply... to avoid ground loops/50hz hum... Please forget the "powerline" concept and just solder the wires in "starlike" fashion directly to the optimized psu cirucit. You could also achieve this starwiring using unpluggable connectors, split a ribbon cable (using e.g. a 10 pin idc connector at the "optimized psu" side) into three ribbon cables each carrying for example 5v/14v/gnd, which are connected at the optimized psu side. The starlike connection ends in three connectors going into the unpluggable core module, the sid module and your keyboard-mini-psu module. By the way, as you probably do not build the core/sid module on veroboard, you can also use lower-pin-count SIL connectors to achieve unpluggable connections at their end (which fit on the SIL headers provided by these modules). Greets, Peter
  10. no problemo, to adapt a known saying... there are no irrelevant questions, only irrelevant answers :-) a) Module interconnections/"power line" I´d recommend IDC connectors, as available in SmashTVs shop: http://www.midibox-shop.com/buy.html They are available with different numbers of pins for all your needs. of course, you also need their counterparts on the veroboards, they look like this: http://www.reichelt....00&PROVID=2402 Regarding cabling/splitting the wires... for the IDC connector, you just insert a ribbon cable and press it together... a small tutorial can be found here: Using these ribbon cables, you can also avoid "Y-Junctions", by just pressing on a connector in the middle of the cable and pressing on another one a bit away... If you only have 2 pins for the power line, this is a bit overkill, but you could create a +14V, +5V, GROUND, GROUND, GROUND, GROUND power line using a 6-PIN IDC connector. The good thing using these connectors is, that they are "coded", so a wrong connection is impossible. And you can separate your modules afterwards (reduces cable spaghetti a little bit :-)) b) where in the "power line" it should not matter where you plug that mini-keyboard-"psu" veroboard... before or after the sid modules... c) 100mA ...to my knowing are enough for a SID-.. That´s why a low-power 78L09 (or ..12 for the 6581 sid) in the mentioned schematics is enough to drive those. As you need 500mA for the keyboard, i´d recommend using two normal 7809s... one on the "optimized PSU" circuit side, and one on your "mini keyboard-psu" veroboard. d) cutting the schematics you need to start at C10 (330uf) and work your way rightwards (using a 7809 ofcourse)... then you will have a clean separate 9V out for the keyboard. Please test appropriate voltages on all modules (SID, Core, Keyboard-Mini-PSU) before plugging in "active/expensive" components, like the keyboard, or any ICs (SIDs/PICs...) Have fun! Peter
  11. Just upgraded to .50... GREAT Changes! Thanks TK.! :flowers: Poly recording feels much better now! And thanks for the BPM LED display! I am very, very pleased with the unit! :thumbsup: After you implemented the BPM LED display, I just wanted to let you know, what was on my wishlist, which for me somehow logically belonged to it (wanted to implement that, when there was time)... These ideas are not high priority at all, and I would first like to hear your comments, and if given a general "ok", I would gladly participate in coding them :-). 1) add a current step LED display for the active track. There are situations, where this would come in extremely handy, e.g. when in live recording "standby" mode, just before hitting the keys, or when unmuting tracks. It would require three more LED digits and could use the same matrix as the BPM LEDs. 2) add a visual matrix track position indicator... using two cheap 8x8 led matrix blocks (ca 3€ each) for 16 horizontal x 8 vertical leds. Aiming for a Matrix-film "falling characters" effect... It would visualize, in which relative-to-the-tracklength step position every of the 16 tracks is currently in. (8 leds vertical for each track, e.g. if step 3 of 16 is played, the second vertical led would lighten up on the respective track column). Maybe it could also use the 8 BPM LED matrix "back channel pins" and thus only require 16 dout pins? 3) add support for separate tempo encoder input pins, that would also accept the "fast2" flag (temporarily push to accelerate bpm changes) and connect to the fast2 line of the other encoders. 4) add a fourth BPM LED digit with a dot, for displaying e.g. "120.3" to visualize small tempo changes . One could nicely fill a full DOUT module with these tempo/position indicators: 8 pins for matrix "back channels", 4 pins for tempo led digits, 3 pins for active track-current step position led digits, 16 pins for matrix step position indicators. I´ve attached a small mockup of how this "tempo/position" module could look like, but am unsure of power requirements (transistors?) for the expanded led matrix (8 x (4 + 3+ 16)). Greets and best regards! Peter
  12. Pirates! Everywhere! *yarr* :-) back to topic... better shop for a "whitelisted" MIDI interface if you want trouble-free operation (or try to convince somebody to send you a GM5 :-)) http://www.midibox.org/dokuwiki/doku.php?id=midi_interface_whitelist Greets, Peter
  13. Hi Karl, The optimized PSU circuit uses the 7809 for 9V DC and adds 5V DC (from the original C64 "brick PSU") to achieve 14V, which will be fed into the voltage regulators of your SID modules - which then convert this down to the operating voltage of your sids (9V or 12V depending on SID type). You could just use another 7809 to create 9V DC from the 14V pins for your keyboard (copy this part of the circuit from a SID module). Or, but I am a bit unsure about this, there could also be 9V available when measuring between the "blue" ground line, and pin 3 of the 7809 in the optimized PSU circuit. In any case, i´d recommend you use a "real" 7809 in the optimized PSU circuit (not the low power variant), to be able to handle the additional 500mA load of your keyboard. Greets and have fun! Peter
  14. The improvements consisted of a) a second 2.200 uF capacitator for improved ripple softening after the rectifier. b) closer installation of the voltage regulator filtering capacitators - you can solder them directly on the voltage regulator pins (this really helped a lot in noise reduction, before, it sometimes picked up stray "switcher" noise from nearby PSUs). Of course, you could do even more things with the PSU, but I doubt that you will hear much difference... Orange_hand is working on a PCB, you could contact him. Greets and have fun! Peter
  15. Well, in this case it might be appropriate to build a new PSU that powers everything... E.g. one like this one: Orange_hand is working on an improved PCB for this design. It has more than enough power on the 9V AC line to power 9V AC driven fx units besides TKs optimized PSU circuit, or in conjunction with a second 7809, drive the keyboard or 9V DC driven fx units. Greets, Peter
  16. Well, there is wavetable support for small (precalculated) bursts of samples - which could probably also be used for very very short formant output... But a full blown speech synth certainly requires some dedication and processing time... Also, TK. said that the PICs in the SID V2 are already fully loaded... So my guess is, that this would probably need to be a (user-add-on) project for the SID V3 on the LPC core... but just guessing here :-). Also, Thorsten has made some speech synth chips experiments lately, so it might be totally viable to regard MIDIbox speech synthesis as a separate (non-sid) project. Greets! Peter
  17. +1 / or you add a small powered usb hub to the optimized power adapter to power the usb keyboard (can be all hidden within the enclosure). Greets! Peter

    That would make for a great pair :-) Green and mean 8580 Red and dirty 6581 Also, 16 SIDs in parallel = geek heaven :-)
  19. Great build + great Pics :-) Congratulations! (& nice, that you put that ViRal3 patch on it :-)) Hope you have lots of fun with it :-) Greets! Peter

    Very nice :-)
  22. That backpanel is a great upgrade! Cool to see someone also implementing that 6.3mm "mix audio out" jack... :-) Also, the fan switch is a very good idea! Greets, Peter
  23. Wow! Great jungle! Great song! (can remember my first jungle party @ 17 or so... wheeeww.. that was soo off world... :-) )
  24. Thanks! The glass was filled with yummy french rosé and as it was empty thrown behind my back, ofc :) The right hand is almost always shifting the filters, the left hand is killing moskitos, arguing with my girlfriend about missing wine and sometimes switching patterns ;-) In retrospective. it was prolly too much ´lohol and not enough different themes, but a good time anyways :) (m00: the machinedrum could do so much more in capable hands, youtubes´ "Machinedrum UW live tweaking" by pixmusic is great and explains lots of it) Greetz! Peter
  25. Hi there, if you use 8580 or 6582 SIDs, heat sinks and some drilled ventilation holes will do (even on hot days :-)) Greets, Peter
