No it is in a Range from +4 to +15V (with the 4 i am not really sure), it simply feeds Q29 with Power -negative Polarity would not make sense- - the Base of Q29 is shortley triggered with the Trigger Signal - coming from Q28, Q29 now switches thru for about 1ms - with the Accent-Voltage - coming from AOUT_LC .... the other Stuff after Q29 are then is a Envelope. (as far i understand the circuit)

complex - but not what aout_LC need...: aout-lc-scheme -i think-

but it ends up this way: lc solder 4 of those chips -with the size latigid mentioned, is not difficult, because it is a resistor it isnt that heat problematic. (the only problem is the conrad price) bend, cut, hold, solder, cut 32 of single resistors is hell of boring work...

i draw the AOUT_LC instead of using them single resistors, i tend to use smd resistor arrays: http://www.reichelt.de/4-Resistors-SMD-1206/BCN16-10K/3/index.html?&ACTION=3&LA=2&ARTICLE=42471&GROUPID=4495&artnr=BCN16+10K should reduce work and space enormly.

1ms Pulse @ 5V ANDéd with Accent Voltage on its max 15V - if you look for example @ Q28 und Q29 - that is a AND function. There exist a website where the HH and CY Section is analysed - its for the DR110...but since the DR110 and TR606 are very simular... it helped me alot to understand dr110 thx 4 the supplys schemes ... tomorrow i will be away 3 days... then the pcb routing will begin.

yes text is ok. the kicad standart library (on my linux...) is a bit confusing... some essentual parts are not logical to find with the filters (naming) and the 7mm thruhole Resistors have no 3D body and so on... anyway, except the library and its lack of a "real" search functions >>> kicad was easy to learn...ha, ok i havent started to draw a single trace on PCB-Editor

TR606 HH+Cymbal? - with Mods(or place4Mods) - cant see it anywhere out there AOUT_LC was the right hit - thx - i will do it that way > http://www.ucapps.de/mbhp/mbhp_aout_lc.pdf I think 8 Bit is enough... and we could use 2x8Bit to make 2 Accents Seperatet, so HH+CY have a own Velocity, and BD SN the other... i think that give more flexibility. @Psykhaze Orginal HiHats and CY have no Noise (i think...)--- thats a Mod - (to have the ability for more 808 hats)

is there any Driver-code out there - in the MidiboxWorld - to use the onboard Audio DAC for CV? (0-127) i just need it for Velocity Control for the Accent of a TR606 which need a Voltage from ~4V to 15V (a little scale with an OP amp should do the trick hardwareside - i think) In the past i have done Accent with a Shiftregister, 8 Varistors and a Transistor... worked well, but steppy. thx phat

@Psykhaze Here my last version with the snare in it... just combine the snare section with the noise section, delete the rest - except some parts of the power part which you will need. I will use the mixer by my side to get the orginally OutputStage-Filtering, and maybe also as some kind of Overdrive..., since we are modular, i will add a Pinheader and a Input Jack on Frontpanel for your BD/SN - to get into the mixdown... for me its easy, CY CH OH are good Triad to mix analog...BD SN are very differnt to each other and to my Triad, anyway i will make Input Jack for that - question is 1or2 Jacks. --- if you have already a Module System, then use the Module Power System Connector, we need +15V and Ground, i will need a extra 5V for the Osciallators and the Core Module (later i will copy that part from you, because i dont have a system supply) we could use a tiny 8Bit core... 32Bit has a DAC onboard, which we maybe could use for Velocity Control. (also 32Bit Plus is, i have already a program for it, but i have also some 8Bit devices, and the code is?t that difference.(MIOS32...string...) 606-Cymbal.zip

update: + noise source which is originally for the Snare Drum - is now mixable to CY and Hats + mixer section - so HH + CY-Mixdown should sound like 606... (filters? Impedance) +part of the original Power Supply Section which give every instrument its very own power source (left downer corner) - i don’t know exactly why they did this... +the 6Square Wave OSCs for the Metal sound: now are tunable with trim pots - in order to tune it to my Setup (A@~432Hz..) (by the way: 6OSCs? 606 interesting...) +added some explanation to the schematics - which i got from thru the internet research... +Add Jumpers for every Output from the different stages - in order to better debug the prototype - and to better mod - and to better tune - and to better make a modular... +pcb will be bigger then excepted - i lost the orginally Part Nrs as a mistake... i only restored the OP-Amps and Transistors - (bad) 606-Cymbal.pdf 606-Cymbal.zip

thx i put there a 2M now. i dont found backgroundimage settings... but a good idea to look at the orginal pcb.

Shematic are all over the net: http://privat.bahnhof.se/wb447909/dinsync/service_manuals/TR-606.pdf Module: CY + HH on one Modular Module (Gnd, +15V), driven with a MidiBox Core32 - the midibox side is already programmed and tested a lot... there is somewhere a Topic on this.... Why only CY+HH.... whell, i have already a TR606 but i only use the Cymbal - and for that it is to big, so why then HiHats also? because they use the same Metall-Oscillators... but maybe i skip the HHs (they take much place) the midibox side i made 2015 here: but sorry shematic are very tiny because of Forum Move and Dead Gallery Pictures....

@Zam thx! i drawed the Cymbal and HiHat Section of the TR606 into Kicad Shematic... the pcb is still left, i dont have the mood right now... but maybe it helps anyone - anyhow... I have used the orginal NRs (R178...) and the MODs for this Section are in it... 606-Cymbal.pdf 606-Cymbal.zip it would help if KiCad whould place the components like or simular like on the shematic... > säcke.

in the picture below - i marked 3 capacitors... i dont understand what that mean: C49 - 1/50 ---- i think that mean: 1µF 50V ... but 1µF is untypically for a unipolar Cap? C47 - 1/50 ---- 1µF 50V Electrolyt cap - could be C64 - 0.0022 .... ceramic 0.0022F? = 2200µF cant be > way to much for a ce rco... (by the way its the Cymbal circuit of the 606)

...this time only one cam...

thx, we will cam more of our weekly jams.... except the beer parts

memory donna summer

short answer: YesNo maybe...but they are allmost the same i have ordered i am still in beta state...give me a week or two... maybe i know more then... in the mean time i have a lot of "if" "maybe" "i gues" it works but not testet on real bongs (only on table...) i have ordered that: EPZ-27MS44 they are not wired (you have to solder a cable) and have no feedback loop, but they have all-much the same Resistance (400-500Ohm) when soldering a wire you have to reduce the heat of the soldering iron...with 450°C you burn a hole in the top-metal...300-350°C is ok but they are very big about 4cm diameter...maybe for a PAD-Solution smaller are a better choise: mouser they are 1cm and used as loudspeaker thery are for high-tone (vs midtone), dont know what that means in the sensoric way, but mine have peak when hit hardest about 5V. your linked piezzo have a feedback-loop - that is sometimes needed when you use it as loudspeaker(the 3rd wire)... but maybe the have use as triggers too? why that? >>>problem: coupling vibrations from one pad to the other: if you hit the piezzo to hard, vibration goes to the other pad... this is no problem for me, because i use it on bongos...they vibrate also to the other bongos but not that much, so i programmed software side a minimum voltage threshold (software decouple) which also reduce the velocity sensitivy a bit... much more of course when you use it in pads triggerpads are a other story...and here comes the Feedback loop in the game > maybe wired on a Digital Input, it helps to find out the correct piezzo element > means if you hit piezzo 1, the DIN Pin 1 gets HI, the software now knows - ignore all other Analog Inputs from the other Piezzos for this moment...so you have the full velocity (stroke the pad)... but that is a bit tricky software side, because- what happens if you hit more pads @ once.... like i said a lot of "if" also the hardware decouple... the stand-the-base-the-case should be very heavy (kilos), it should not vibrate when you hit a pad, because every vibration give Piezzo information on all other pads then the pad, on its backsidein a hole of diameter about the diameter of the piezzo, in it the piezzo. and between them case and the Pad should be a very good shock absorbing material, which? > dont know? but they should make a good decouple job...and it should not be to loosy because loosy means vibration - and vibration make fail-triggers on the other pads - a internet search for such triggerpads for drummers should bring more information...but thats not my site...i am on bongos there are other problems. just my 2 cents

The Test Equipment This Kroko cand hold on surfaices up to 4cm (piezzo - clamp) 572a2859eefc1- The Piezzos dont need Active components... The Electrete Mic- Stands ---- the will be placed inside a bongo (since a bongo is open at the ground) Midibox Stuff...
