Very nice work! Noticed you used banana plugs instead of the matrix panel. From what I've read about the matrix panel, the banana plugs will be more dependable and have fewer problems than the panel. _________________ -- Kevin http://kevinkissinger.com

I use the word SYNTHI in the loosest sense of course. All my gear is bananas. Banana jacks are honestly the closest thing to religion in my life, I will proselytize them forever. I often have 100 cables in my bag for gigs, impossible with phone plugs,, and minis I wont even comment on.
Hope to post some video of this thing eating its own head when I get a new camera. The filter is really spectacular and I dont think I even have it trimmed in proper.

I've never had problems with minis -- I've always been amazed at all the bad press that mini's receive.
My use of mini's is not particularly scientific -- it is simply because my original Aries synth (a kit synth) used mini's so I've stayed with them for compatibility. I've seen excellent results from bananas, 1/4", and minis and I think that, while each format has particular advantages, it may boil down to preference. _________________ -- Kevin http://kevinkissinger.com

DIY spring reverb
Top Top wrote:
The spring reverb is it's own effect. It's made from the springs in those "echo mic" plastic toy mics.
That sounds quite nice. I actually got myself one of those echo mics
a few years ago to do just that but haven't gotten to it yet. At least I
know now it's possible. I do wonder how you did it though, any
chance of some inside pics ?

Solar Sensor Subject description: Pimped LDR
Here's one of my latest builds, I wasn't sure if I should post it here
since it's not actually some sort of instrument music making thingy
but it will be used as a controller so I guess that's ok too.
It's sort of light to CV controller made to react to changes in sunlight
(or other light sources). I can adjust the gain to make it really
sensitive so it reacts to minute changes in light (like slowly moving
shadows from plants), it has a control to adjust it to the amount of
light and a control for the reaction time from very fast to very slow
(glide effect). Output varies from 0 to 10V and is indicated with the
LED's.
I couldn't come up with an original name and really wanted to finish
it so just simply called it "Solar Sensor". I also did something
different with the front this time. Usually I use transparent but a bit
frosted looking adhesive foil that's specially made for making fronts.
Problem is that it's a bit expensive and I never seem to have
enough when I need it so I always have to order it (and I don't like
waiting when I'm working on something). So this time I just used
woodglue. First on the backside, and after it was glued on I also put
a coating of it on the front. I have to say I'm pretty happy with the
result, though next time I'll try a little roller instead of a brush.

info on predictive synth
inlifeindeath wrote:
very cool phobos! can you tell me a bit about your predictive synth? i'm loving the sounds but i can't figure out what's going on!
Thanks
explain the predictive synth,. hmm where do I start.
well you could take a look at this: Predictive Digital Music Synthesizer
(if you haven't allready). It's an interesting read.
To be honest i don't fully comprehend it myself,.
But the version I made is a pretty much a simplified version of what you
can find at the above link.
On the left side of my predictive synth is the first version I made. I
was curious of what it would sound like but it looked a bit too complicated
to do on breadboard so I build it on perf right away. I added jumpers so I
would be able to do some changes but that turned out to be pretty
useless. On the right side is the second one,. which I tried to do with one
chip. But because it's a very short sequence it sounds kind of boring so I
added a binary sequencer (that's what the little patch cables are for). I
don't think I have a complete schematic but I'll look if I have something.
Maybe I can add some comments to the video so it's a bit easier to
understand what i'm doing there. _________________ "My perf, it's full of holes!" http://phobos.000space.com/ SoundCloudBandCampMixCloudStickney SynthyardsCaptain ColliderTwitchYouTube

hip bass drum (from this forum.... sounds EXCELLENT)
Hey Bubzy, do you have any samples from the Hip Bass Drum? I'm working on a drum synth right now and am curious how it compares to some of the ones I'm building (Bass++ etc.)

I just finished up a super bloated ring modulator thingy in a box. It has a transformer/diode ring modulator section based on Ken Stone's active ring mod, four simple LFO's, a Thomas Henry VCO-1, two Thomas Henry VCA-1's, a Thomas Henry VCF-1, an Electric Druid tap LFO, a Micheal Barton (Boogdish) pic quantizer and an envelope follower based on the one from Ray Wilson's envelope filter. And lot's of wires inside, i could barely close the lid!
Lovely work coming from everyone here!

Hello , just finished my Ian Fritz / Bridechamber pcb's this weekend , panel done , drilled , assembled .
Double well chaos / 5Pulser / some multiples (handy).
The chaos used as a cv generator is great fun , i included a 6 way rotary switch for a selection of polystyrenes i had lying around for C1 and C2 cap selection, M medium setting is the standard 1N from the circuit down to XXL ... 680N for interesting sweeps.
The 5pulser is great fun as well, i like it alot
i'll post some short sounds in a few days .
Here is the panels to match the rest of my modular .
Thanks for looking
Dave.

finished tonight needed more space ...2 dual mfos ADSR modules i built in 2005 condensed into a quad ADSR with 2 outputs and i've ommited the level out pot , all my cv in's have attenuators... this was a fairly easy transplant job with only a few hours soldering needed

Here are some other recent things. There is an MFOS 16 step sequencer, sound lab mini-synth + and an MFOS phaser on one big panel.
In the modular cabinet clockwise from top left there is
-an MFOS quantizer and two 4 input mixers
-dual MFOS ADSR's
-an MFOS VCLFO
-two simple LFO's
- an MFOS state variable filter
-a module for bringing guitars or other instruments up to synth level, providing boosted clean signal out, squared out and octave down squared out along with gate and trigger signals, based on the MFOS sub commander mostly
-a Buchla low pass gate and Thomas Henry VCA 1
-a CGS active ring mod and two Thomas Henry VCA 1's
-half of a working mutron bi-phase type phaser with selectable number of phase and feedback taps, and voltage controlled normal or inverted feedback
-and a rehoused synthesizers.com midi to CV with two simple glide circuits and some multiple jacks.

I probably won't get around to making any video's of the ring modulator from a few posts ago, due to laziness, but maybe a quick description of some of the things about it that i especially like.
I brought the trimmer for carrier rejection out to the front panel on a ten turn pot, this lets you either trim any bleed though out or dial some back in, which is really cool, especially when sending the same signal to both sides. It makes some very interesting distorted/octave up/folded sounds this way. The scope shots show the internal VCO's sine wave being fed into both sides of the ring mod, at varying levels and with varying amounts of carrier bleed allowed through, under voltage control with the internal VCA's. I can't ever trim the bleed through out completely, but it gets pretty darn low and there is usually a VCA after it anyways.
It makes a nice little single VCO-VCF-VCA synth on it's own, with jacks for voltage control of the VCF, VCA's and 1v/oct for the VCO.
I have not tested this part extensively yet, but it has a jack in for syncing the picLFO to an external audio or clock signal, a bass drum being the most likely candidate. There is also a jack for triggering the envelope follower from external audio.
I also want to say thanks to all the designers of these circuits for generously sharing their work, so thank you!
