hmm, just realised an LCD would be needed to see the BPM value as u adjust the pot...:/ T, could 3 seven-segment LEDs be used instead? If so, could ya give us a few pointers with the code ;) Or perhaps, make the BPM pot transmit MIDI so it could drive a text fader with the bpm values in logic? Best... Dan

Okay... A simple Logic macro made for Magic MIDI Delay: And the LSO: http://www.notapplicable.co.uk/mbhp/mmd.lso Requirements: 1x18F Core 1x10k Pot (Control BPM value) Here's the syx file for the adaption of MMD to a single pot if u dont wanna go in MPLAB and rejig the code urself: http://www.notapplicable.co.uk/mbhp/main.syx Njoi ;) Dan

;D Hey T... Yup, project made and sysex'ed all fine ;) workin just dandy with 1 pot controlling BPM value... On to the logic enviro now ;) might have a problem fitting this in my midi setup tho, havnt got much i/o atm - even having just made a midi merger and gameport midi interface. Still, i'll see how i get on and post the results as and when ;)... Best... Dan

nice idea robin - just seems for that amount of effort (cutting the same top panels 3 times over - wood, paper then plastic) u might aswell just do it once with 2mm ally... as you say tho, stick to whatcha know ;p hope to see sum pics of ya box soon! Best... Dan

have u adjusted the contrast pot for the LCD? HTH... Dan

i've done my own panels with the following: Dremel with various bits - mainly router and cutting discs. Regular powerdrill - when using best to use it in pulses and only apply pressure when the drillbit slows right down, u get nice clean cuts like this. After drilling it's just a matter of using a reamer for the bigger holes (midi sockets etc) and filing everythings else away with mini files (draper does a nice mini file pak). Make sure u use plenty of oil when cutting metal, and also that u have nice pre drilled (i use a mini hand drill like for pcb breadboards) pilot hole before drilling holes for pots and leds - ensuring everything is aligned nicely at the end ;)... Once ur panel is done, give it a quick spay of a decent car paint (i like a chrome effect), then add ur artwork via decal paper (havnt had much success with this - prolly down to just wanting the box up and runnin;p) before finally spraying a few (and i mean a few) coats of accrylic spray varnish - i use summin called crystal clear, it gives a glossy finish, but a gentle rub with sum wire wool gives a nice matt finish... Check S.Thomas' page for more info on the decal - link from ucapps site... Best... Dan

heh, dont worry about it - i also used 2 x 1nf caps on my first SID box (still workin) i think it just made the filters sound a tad different, i sinced changed them to the recommended ones for the 6580 just in case ;)... the SID does run hot - that's normal ;p whack a heatsink on if u really wanna, i havnt bothered tho... best...

hmm, it appears the zip doesnt contain the project file for MPLAB so i cant edit mmd_init to change the AIN tag to umuxed mode and then assemble a new hex file to test etc... Would this be correct: ;; initialize the AIN driver movlw 0x01 ; use 1 pot call MIOS_AIN_NumberSet call MIOS_AIN_UnMuxed ; don't service multiplexer interface the ain.inc file could be left as is i guess as pot 1 is already assigned to bpm... Cheers... Dan

Hey T... Just been having some fun with this lil app - very nice ;) I'm trying my best to impletment it in my current setup - hard with one midi i/o and a midi merger handling a keyboard, 2 midiboxes (3rd on com) and a SID! So, i was thinking - could it be possible to just have a single pot connected direct to the core just controlling the bpm value - as i cant see this is implemented via ext midi in main.asm. Then mebbe just have 3 seven-digit LEDs to display the bpm and no LCD - possible? I'd then whip up a logic enviro to control all the other params and display info...;) Would be a great primer to MIOS - 1 core, 1 pot, 3 7digit LEDs...and if ur a logic user an enviro to go with it...:) Great stuff! Dan

heh, dont let my post count fool you - i'm not clued up on electronics at all and have only been able to put my boxes together with the help on this forum (and TK's patience! ;p)...i'd still be twiddling me doepfer pocket control otherwise! :o (which i've since parted with ;p)... best... Dan

okay, it seems if i adjust the contrast i get the ready msg and am able to send and receives syx again (with the new pre f/w): however, after changing lc_int to: #if LCD_USE_SECOND ;; use a KS0108 compatible graphical LCD with inverted chip selects movlw 0x01 movwf MIOS_PARAMETER1 movlw 0x01 call MIOS_LCD_TypeSet #endif no joy :(...also tried: #if LCD_USE_SECOND ;; use a KS0108 compatible graphical LCD with inverted chip selects movlw 0x00 movwf MIOS_PARAMETER1 movlw 0x00 call MIOS_LCD_TypeSet #endif and still no joy...:( still, at least we have another word now!! ;) tada Dan

one more thing, i've noticed that since burning that mios pre f/w, the core doesnt send out that sysex msg it used to with the previous MIOS when u first apply power - so perhaps the new main.syx i assemble and sysex to it isnt getting through...another reason is that the sysex: F0 00 00 7E 40 00 0D 02 00 0B 12 00 00 00 01 00 00 00 00 F7 doesnt return the LCD type as it did before... However, when using the previous MIOS the sysex is transmited/received fine... ???

hmm, my leds are working this way too - i thought that was how it was spose to be :p... best... Dan

Hey T... The letters only appear breifly when i move the contrast pot back and forth, then they disappear - apart from 'Klose' which seems to stay...this is still surrounded by the mass of pixels... I tried the new LC f/w with the code u suggested both times - changin lc_init.inc to suit and then reassemmbling the hex and then sysexing... each time it didnt make any diff... Is there any way to chek the hex file to make sure it's compiled properly? Dan

heh, i know was jumping the gun a lil, but having the 4 SIDs sitting in they're refurbished C64 case makes u wanna just get it all singing and dancing ;) I'll wait for the proper firmware and application to land ;)) Cheers Dan

whoops, smoking pot (ahem ;p) issue sorted... forgot gnd and Vss were reversed. After assembling again in mplab with the changed code I still get the same result, infact mebbe worse again - cant make out any text :/ No. Best.. Dan

Hey T... -14.36V. I'm also still gettin smoking pots when it;s just connected to Vlc and Gnd :/ I'll try the CS select thing u mentioned aswell... Thanks... Dan

argh!!, ya see this is another reason i post alot :p just gonna paste the link itself now: http://www.notapplicable.co.uk/mbhp/image02.bmp
