  1. a little wavetable help please..

    Aah thanks! I understand now! The $00 $20 $40 $60 columns each correspond to a different wavetable.. Thanks a lot :-)
  2. a little wavetable help please..

    Thanks TK..   I'm still scratching my head and wondering how you can see what is going on from that table of numbers - I'm scanning the parameter chart and still no clue..  http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fapps%2Fsynthesizers%2Fmidibox_sid_v2%2Fdoc%2Fmbsidv2_parameter_chart.txt   I'm looking at one of the tutorials - this one is how to make a Sync Lead, and I understand what's going on here.. OSC3: enable the Saw waveform and transpose by -12 OSC1: enable the Saw waveform and set the sync flag ENV1: depth=+63, Attack=0, Decay=72, Sustain=0, Release=0 LFO1: Rate=24 Wavetable: Track1 assigned to CC#72 (LFO1 Depth), adjust the Wavetable Rate to 5 and enter following sequence: STEP CMD #1 00 Play 40 01 Play +00 02 Play +00 03 Play +00 04 Play +01 05 Play +01 06 Play +02 07 Play +02 08 Play +02 09 Play +04 0A Play +04 0B Goto 01 So having set LFO1 to modulate the pitch of OSC1, the ADSR of the patch and configuring the parameters of wavetable 1 (Track 1 assigned to CC#72), I hit the WT Editor menu.. And I'm presented with this:     How do I input that series of Play / Goto instructions? And where do I find the hex value for a 'Play' / 'Goto' operand?     Cheers for your patience, I am but a SID padawan..   Carl
  3. a little wavetable help please..

    Hi,   I'm struggling to figure out how the new V2 Wavetable editor works.. I followed the tutorial to rip the instruments from a .sid file, and ended up with this..   Wave Transpose Att Dec Sus Rel 10       +00 (+00)   0 112  80  72  +00     +00 (+00)   ...  ...   ...    ...  +00     +00 (+00)   0 120   0    0  10       +00 (+00)   0   0     0    0  00       +00 (+00)   0 112  80  72 04       +31 ( 31)    ...  ...    ...   ...   and so on..   However, I can't seem to find where the command byte is (i.e. PLAY, GOTO), or where to put it in the SID wavetable editor..   Could someone give me a quick and dirty explaination of where to input these parameters in the control surface's WT editor? (guessing it's the $00 $20 $40 $60)   Cheers,   Carl
  4. Hi all!   Thought you might like to see my synth! It uses a MB-6582 as the core, running through an SSM2044 filter module, controlled by an Arduino..   I only just realised that the Midibox SID has an analog CV out, but it was too late! I ended up coding an Arduino with a seperate envelope generator and CV out, with two modes - one is a dirty PWM output that mashes up the CV through some filthy capacitor filtering - this is what I'm using in the video clip.. I've since added a seperate DAC chip output for a cleaner CV, but since I liked the sound the PWM filter makes, I kept it, and added a switch to toggle between both modes.   I also cannibalized the C64 power supply, so now the whole unit all runs from a kettle lead on the back of the box..   There's some big faders on the left controlling the ADSR, which makes hands-on control of the filter a piece of cake, which is crucial when you're in the midst of a funk jam! There's a MIDI controller built into the box, and the Mod Wheel also controls the filter..   Excuse the MDF box and marker pen labels - presentation was never my speciality! I think it fits the disgustingly mighty sound this monster monosynth creates!   Here's a clip from the reCyclotron 64's first outing last week at my Groove Night.. Enjoy the filthy sound of four SID chips running through an SSM2044, into a Roland Jazz Chorus, with some extremely funky British musicians!   And big up TK and Wilba for some awesome electronics x     Carl
  5. Chaos Matrix

    Hello peeps! Did anyone ever successfully get this project working with a Matrix 6? The question's been asked a couple of times before in this thread, and other than a nod towards using a Behringer controller, very little was said.. I've got some old MB cores lying around from my SID-making days (successful they were too!), and I want to build a controller surface into the top of my Matrix 6 keyboard.. Best wishes, Carl
  6. Bassline engine techno session

    Just a little video of us noodling with a few of the knobs in the bassline engine and getting a feel for the way the Midibox SID works.. Except the session turns into a bit of a rave at the end :ninja: What you're hearing is a MB-6582, running two 8580's.. What we discovered is that each core can run another two basslines (and the third oscillator can modulate them) - so I'm currently looking to pack her out with a few more SIDS! Oh yeah, and the feedback pot is definately a necessity! I bought a 470K pot from Maplin which I'm still waiting on *grr* Enjoy a little Chiptune-Techno, South-London style, as professor Timmy Orangafruup demonstrates the intricacies of the MB-SID in his own unique way.. Oh, and a massive thanks to TK, Wilba, Smash and the rest of the cats who make these things possible, and inspire us all to learn the dark art of electronics..
  7. Specs + UK Supplier For MB-6582 Feedback Pots

    I figured the ones from Maplin (the 470k linear ones) are fine for me, but then I'm bodging my whole thing into an old C64 case and I want the knobs on the front panel, along with a patched in delay pedal :-)
  8. Herbie Hancock and the MB-6582

    Since I just finished my Mb-6582, thought I'd share a little clip of me jamming along with Herbie.. Enjoy! Carl aka The Red Reverend x
  9. Interconnection test troubles

    So, I bridged the Vreg and I'm now sending 12v straight to the SID.. With a rather substantial amount of background noise that I'll deal with later, I'm getting the test-tone loud and clear! But now, once I upload 'setup_6581.hex' - the core reboots, and says "Launching CS" It then flashes what I assume to be an error message, and reboots.. And repeats this over and over again.. Apart from once, when it booted up normally after I left it for a while (at which point the sid wasn't powered so I couldn't check if was working :-( - and after that, nothing.. Maybe i've blown up my PIC after all.. Other apps upload OK (i.e. setup_8580.hex, setup_MB6582.hex) and go into synth mode, but setup_6581.hex - the one I need - just keeps rebooting) Any thoughts on this?
  10. Interconnection test troubles

    Hi Nils.. Firstly - yeah, I'm using a 6581.. I performed the multimeter test between the vreg ground (middle) pin and the vreg lineout (pin nearest the SID), and i'm only getting 0.2v. With the multimeter negative on the ground lead of my 14v power source, and the positive on the MB_SID 14v in pin, i get the correct voltage, so I can see that the correct voltage is reaching the MB_SID board. And with the multimeter negative on the same ground lead, I can see the same 14v reaching the voltage in of the vreg - so the correct power seems to be reaching it.. I replaced the Vreg with another 7812 - and still I get the same problem.. So although I assume isn't the vreg that's causing the problem, since I replaced it and still get the same result, I can't work out what the problem is, since the correct voltage seems to be reaching it, yet the wrong voltage is being given out.. Maybe part of the trouble is I'm not sure which ground lead I should be attatching my multimeter to - and as a result I get different results..
  11. Interconnection test troubles

    (Here's a diagram showing what voltages I have on the 14v power section of my SID board..) I hope someone can help - I think this is the final hurdle before I finally get some sound out of the beast! Could I take out the 7812, and bridge the top and bottom holes, and put a direct 12v through this board from a Wallwart? Or is this a bad idea?
  12. Interconnection test troubles

    GGGGRRRRRR!!! For some strange reason, I'm now only getting 10v on the SID 12v Vdd pin.. I traced it back to the SID board - i've got 14v coming in correctly to Sid:J1, and it reaches the topmost pin of the 7812.. But the 7812 is then only giving out 10v.. I replaced the 2200uf Capacitor, but it hasn't made a difference.. Strangely, I get 14v on the SID:Vdd and SID:Audio Out/In when the core module isn't turned on, but it goes down to 10v as soon as I power up the core.. I tried the testtone, and there's no sound coming from it now - I lost my super-quiet high-pitch whine completely, (except for the high-pithed whine I'm now making out of sheer frustration!)
  13. Interconnection test troubles

    Aha! I just noticed that CS# is supposed to be giving out 0v when tested.. It lives!! So let's see what sonic delights we get out of this beast..
  14. Interconnection test troubles

    Hi all.. I'm currently performing the interconnection test between the my core and sid modules - i've got a steady 5.24v on every pin except for CS#.. I've continuity-tested the connections from the PIC pin RC5 to the SID pin CS# - and the connection is good. So i checked the voltage on the PIC pin RC5, expecting it to be sending out the 5.4V, but i can't detect any voltage on it. Is this an indication that my PIC is broken? (I did smoke it a little with a poor power connection, which I've now fixed) - and every other function of the PIC appears fine. I'm guessing CS# has something to do with the clock source for the SID, so I can see that potentially I may have fried this vital function when my SID started to melt.. Any thoughts? Is is it time to call Smash and ask for a replacement? (Hope not! I'm soooo close to hearing the first phat sounds out of this leviathan!) Cheers all!
  15. I'm having problems getting my SID to work using the testtone app - sometimes when I turn it on it doesn't work, but after I turn it on and off a couple of times it works again.. Did you manage to make yours work properly, every time?
