Ich bin selbst so neu hier daß ichs auch nicht mit Sicherheit sagen kann, aber ich glaube bei Encodern gibts nur ein und aus als Ausgabe wie bei Schaltern, die Drehrichtung wird dargestellt durch verschiedene Phasenlage (oder so ähnlich)

that has nothing to do with voltage. just look that your psu gives at least the mA that are required by your components. some more's good too to have reserve. but taking e.g. more than double of what your circuits draw would simply be waste of energy.

i like that idea, more independent controllers! could that be wired internally or would one have to connect them via midi merger?

hi! i believe the screw holes in the frontpanel are discussed in Doug Wellington's 6582 fp group buy thread: http://www.midibox.org/forum/index.php/topic,11073.0.html (if that's what you meant)

thanks nILS, great links!!!

has anyone a schematic of the old electro harmonix mini synthesizer? no matter which version (with or without delay/glide bar) or knows where to find it? thanks

i'm on the list too. thank you! decided to go for custom design.

:) good to know, thank you!!

i'd like to ask: is this kind of pushbuttons regularly debounced? this is never mentioned on sellers websites. is this because "everybody knows they are" or because they are not? (hope i can use them, i've ordered some)

update: now all PCBs from Mike's are soldered: 1x CORE, 2x SID, 2x DOUTX4 with the bridges for modulation matrix and 2x DINX4 + 1x DINX2 for step C ctrl surface. i just learnt that i don't need the rectifier / vreg circuit on the core pcb when using the original C64 psu. so i'm thinking again about using trafos for each voltage, depends on finding some quite fast... 2 important questions for today: a) i've searched everywhere in forum/wiki/uCapps for a description of the transistor driver circuit for the LEDs in the modulation matrix, but haven't found anything... does anyone know where to find information about that? b) would the use of low current LEDs in the MM require change in resistor value (220ohms)? thanks!

here's the link to the list: http://www.midibox.org/dokuwiki/tk_gm5_bulkorder

doesn't the TB303 already have an analogue sequencer inside? otherwise the DIN SYNC (25 ppq signal) wouldn't be necessary i believe. as far as i know there are people who built x0xb0x. they surely know all about it in detail. try the forum search function!

thanks a lot, it's very helpful!!!

well if jimh54 is sure about it then I could buy the pcbs from him. I'd take over the SSMs DW ordered for him, too, but BOTH just in case DW agrees to that solution. and not this month- so everyone would be happy this time...

yeah, that answered my questions, too! thanks seppoman!

i haven't read that much about the normal AOUT module and SHX8. but i think it should already work with MB64 and MBCV. but the ssm thread says that the sid option is much more powerful than the mbcv because of the modulation matrix or having the filters controlled by the env, full automation. you could still turn the knobs as well. i don't know if it is possible to reassign 16 encoders to control 8 mono or at least 4 stereo ext, but if not you still could use 1 core for 1 pair of encoders i still don't know more, but i'd like to find out more about it too...

hey, just found the answer in the original SSM thread: http://www.midibox.org/forum/index.php/topic,11790.msg95666.html#msg95666 if i understand this right, you can hook 4 AOUT_NG modules on 1 MBsid V2.

as far as i know the best application to use the ssm circuits with is the sid V2 because you can control the ssm even without a sid connected. but i don't know how it is done exactly. i also don't know how many AOUT_NGs you can control with one core, i think i'll have to read the ssm2044 thread again, i think i have already read that question there...

hallo matoz, c'est un projet très interessant, une box des filtres (?) avec des ssm... je ne comprends pas des filtres analoges et pas beaucoup francais, c'est mauvais... mais si vous voulez on peut parler plus beaucoup à ce projet en anglais (aussi)?

the idea is good, it's like on an analogue synth. one would need to rewrite parts of the menu structure to be able to skip menues by touching an additional menu button. so that's far too much for me atm :) but perhaps some day... now i've looked which buttons are not used in button-encoder combinations like the menu button for example. i'll leave the menu buttons and enc as they are, the same with the SID nr and up/down & shift. but for all other buttons like these in osc, env, filter and lfo section i'll use the buttons provided by my encoders without having to rewrite code for that purpose (at least i hope so). that's similar to how Vinyljunkie has done it several months ago as i just found out by doing few searches: http://www.midibox.org/forum/index.php/topic,12065.msg104668.html#msg104668 but of course, having the control analogue-synth-like would be very great, but to have it perfect i guess we'll have to wait at least till the 32bit era, perhaps you can then use some more displays too (dreaming)

i like smash's proper pcb design very much, too! very clean, it has even room enough for better connectors. here's mine, less clean performance i must admit... n00b after all http://www.midibox.org/forum/index.php/topic,12947.0.html

yes that's plausible, i'll mount them on-board. i'll always have midi connection between my devices anyway. so thanks!

thanks! i guess it would make more sense to leave only one empty, so i could change one eeprom, that would be more than enough for easy access. does it matter which are stuffed then?

hi! i have got a special BankStick- pcb from mike's with room for the full load of 8 eeproms. but there's no room for mounting holes so i had the thought to put it in a simple little case. can someone tell me if it is possible to have 8 BankStick eeproms on an external PCB (and 8 inside the SIDV2) so you could swap the memory of 8 eeproms (with a switch for example) ?? has someone already done this?

hi! well i soldered my first core these days too & wondered about whether the crytal has a polarity or not. but there was nothing to find on uCapps so i put it in like a resistor. all other parts with polarity are mentioned several times as such on mbhp so i hope it was right. but one could surely look in google... but all ICs are polarized. there's a groove at one end. to the left of this groove is pin1 usually. i think the IC will fit the socket in every direction. but it surely is better to put the socket in the right direction in any case. could be someone's changing the chip in the future who doesn't know about. good luck!
