Now optimised for all good smart phones!!!!

Well, mostly all of it, still having problems with audio… Let me know if you find any other faults.

for the time being all comment postings are closed, please email me for any info or discussions. sorry for the inconvenience.

my dr-110 arrived last week and i promptly set about dismantling it to modify. the dr-110 was one of the last analogue drum machines produced by boss and was severely lacking in control over the drums. as standard it came with accent, tempo, volume and balance control.

there are two great sources of mods for these machines, dave magnuson of resonant frequencies, for which the website has been down for some time, but there’s copies of the pages available to download from the electro-music forum, and a guy called rob from this page.

i’ve added mods mainly from daves, and a couple from robs huge list, and the results are phenomenal! i know have 13 additional pots, and the whole lot is being rehoused in a mini flight case thing i found in maplin for a tenner in the sale.

i’m writing a page on the mods i did so check back for the results.

my trusty HR-16 (or one of them at least) has bit the dust. think i have a fault in the master reset circuit, according to the service manual.

it was the one with the led’s as well. what a waste.

i’ve been using the arduino for midi input and output for a while now, mainly using kuk’s input method, output is easy enough though. midi input had me stumped for a while, but he found adding 100k resistor to the base of the phototransistor of the optoisolator created a stable response which sorted it out.

theres alot you can do with variations of his code, and many people have used the circuit to build midi>cv convertors for analogue synths, but at the moment i’m mostly interested in building a clock source for analouge/digital sequencers so i can run them straight from the output of my HR-16 or tr-505 without the need for a computer based midi sequencer. the basic idea is to receive a midi clock byte and advance the count of a 4 bit binary output from the arduino to advance the steps of a multiplexer ic based sequencer.

midi clocks output 24 pulses per quarter note, so this needs dividing down to get the step response you need. the ever useful and highly inspiring code from littlescale comes in handy here!

more soon.

i shall be circuit bending a seal! (cheers phil!)

no seals were hurt/damaged during the making of this clip… and before i get any comments about animal cruelty, i wouldn’t even get it past customs shoved down my pants in the first place, unfortunately. ;O)

although i am intriegued as to what the fuck they do with the blow torch in the dying seconds of the clip!

sorry about that folks, but we’re back in action now…

some thoughtless tweaking…

well they are finally here, check them out.

well, i have a fair few things on the old bread boards just now, and lots to build for various folk, here’s a quick run down of whats coming up.

analogue dub siren – 555′s just dont cut it and seem so very popular for these things for some reason, god knows why. anyway, the pcb’s are off for fabrication as i type, so kits and units will be ready in the next month.

amdek pck100 clone – the pck100 is a wonderful little analogue drum/percussion synth, and with a few mods it really kicks out some nice sub bass noises with huge decays!

roy gwinns guitar effects processor – throbbing gristles chris carter made this schematic hugley popular and was part of their signature sound, but again, why just clone it when you can modify it! the bread board prototype is great, and with the use of a wave shaper lfo instead of the original lfo from roys schematic, it really cranks out some cool sounds. (mervyn, i’ll have this finished for you soon, i promise!)

pattern synths – the first batch are being finished this week and should be ready for sale, and samples, videos and a whole page of their own is coming. some of jamie and lenny’s tunes with these things are fricken quality and should be out on industrial strength records at some point.

sequencers – a simple and effective way of building sequencers for resistance controlled oscilators, such as the simple oscillators in the synths section and the weird sound generator by ray wilson. 4, 8 and 16 step versions planned with forward/reverse and pseudo-random counts, which can be easily adapted for control voltage.

and if all thats not enough, an open source, arduino based modular midi controller.

why are there only 24 hours in a day, and why do i have to work for 8 of them?

i’ve been updating the synth pages with some schematics for cmos based noise boxes.
