Pics and Build Notes on the Knob Laden noystoise YAMAHA PS3 V2

You might remember the knob laden Yamaha PS3 V2 video posted here. For those interested on how it was done, noystoise just posted some pics and build notes here. Beautiful work. It's hard to believe there is a Yamaha PS3 under there. It looks like a Roland JD-Xi on steroids.

Noystoise YAMAHA HS200

Published on Sep 8, 2015 noystoise

Some pics and initial details via noystoise. Be sure to click through for more.

"The synth is based off of a Yamaha HS200 that the musician had owned since he was a kid. the keyboard is a regular piece of his performance rig, so the finished product needed to stay compact. i had never had the chance to play an HS200 before it was shipped to me. the keyboard is actually pretty powerful for its size. it has 5 timbres, 4-note polyphony, and sustain. the keyboard had some issues, as most toys of this age usually do, but after a good tare-down and cleaning, the keyboard had a lot of potential. one interesting thing about this keyboard was the auto-power-off function. it was actually a separate dedicated IC made by Yamaha. never seen that before. needless to say, i took it out of the circuit..."

"The HS200 itself has a pitch control circuit that can be modulated manually, by the LFO, by the EG, or by the CV input jack. the range is pretty limited but enough to get some great warping sounds. the keyboard also has a 5-position switch to select the timbre, as well as a single on/off switch that engages the sustain mode...

The LFO is pretty cool. it is the same dual op-amp triangle wave VCO i use a lot, however, this time i added a triangle-to-sine wave-shaper after. the wave-shaper can actually be swept from triangle, to sine, to square-wave gradually. this is a great circuit to have in the toolbox. more fun to play with than a three position switch. might have been cool to add a CV input to control the wave-shape. maybe next time. the frequncy of the LFO can be controlled manually, by the EG, or by the external CV input to the LFO. the LFO has a depth control knob that controls the level to the internal parameter it is set to. the LFO has a CV output, but like the EG CV output, the signal is output at full, and can not be controlled with the depth knob. the LFO has a 5-position slide switch that can be set to modulate either the HS200 pitch, 12db filter cutoff, echo rate, echo HP filter, or echo LP filter..."

MQ1 custom synthesizer for MENG QI

Published on Jun 23, 2015 noystoise

more info at www.noystoise.com

The following is just a small portion of the full post on noystoise and a couple of pics to give you an idea of what went into this custom synth for Meng Qi, know for his own designs, including modifications of Ciat-Lonbarde creations.  Be sure to see the full post for full specs, build details and more pics.

via noystoise:

"After some back and forth, we came up with a general formula for the synth-to-be. it would be comprised of two sequencers with capacitive-touch sensors, two voices with analog filters, frequency modulation, reverb, a few modular inputs and outputs, and a Meng Qi logo. knowing that this would likely turn in to a pretty large and time consuming project, i quickly got to work designing synth. the project did end up taking almost two months to design and build, but actually, it could have taken much longer and i am actually kind of impressed with how quickly this one came together, considering the complexity of the build...

The signal path of this synth is pretty straight forward, but extremely fun to play. basically the circuit starts out with two square wave voltage-controlled oscillators. the oscillators have a pretty wide range, from high to low. I probably should have measured.. the oscillators' pitch is controlled by its own respective 8-step sequencer. each step can be manually tuned with a pretty decent amount of stability, considering the range. the sequencers are driven by a single clock signal, or they can be triggered individually by an external gate input via the respective input jack. each clock input signal, whether internal or external, is sent through a frequency multiplier, and then a divider, before being sent to the sequencer clock input. the multiplier has four settings; X1, X3, X4, and X5. the frequency multiplication is achieved through the use of a CD4046 phase-locked-loop circuit. at lower frequencies, the PLL takes longer to latch on to the multiple, but eventually it ramps up or down until it is in sync. it is actually kind of a neat affect because the sequencer will sound kind of glitch for a while, and then gradually falls into sync, and then totally syncs up. this made it tricky for the external input though, because the PLL is looking for regular intervals, so if you were manually triggering the sequencer or you had a pattern sequencer running to the input, the multiple would be all kinds of crazy.."

New Synth Gear and Makers in January 2015

After this year's massive New Years post, I thought it might be interesting to see how many new makers and new gear announcements we received in a single month.

This may or may not become a monthly theme on the site depending on interest.  If you think it's worth while, leave a comment.

At a high level we had 12 new makers, one new old maker previously never featured on the site, and a whopping 193 new synth related products. Check out the module list below.  The list is a combination of what was either announced or released this month.

DRUM SYNTH

"This project began in early December of 2013. it was originally a commission, but the deal ended up falling through, and i never got paid for it. hopefully i can find someone out there to buy it from me to make up for my losses.

The original concept was based around the Synare3 circuit. the Synare3 consisted of two CMOS oscillators, a white noise generator, a four-pole resonant lowpass filter, a voltage controlled amplifier, and two envelope generators that modulated the filter cutoff and VCA amplitude.

My task was to build a modern variation on the circuit that would enable CV/EXP. PEDAL inputs to the oscillators, filter, and VCA. this would mean replacing the CMOS oscillators with voltage controlled oscillators. i was also asked to add the ability to 'transpose' the oscillators frequency range, create multiple waveforms, add a 'crossfade' between one oscillator and the noise generator, add a line-in mix, and a pushbutton switch that would fully trigger the envelope generators..."

Noystoise NTO2 Mini Joystick Synths

Published on Aug 20, 2014

I have to say these are pretty stinking cute and do sound great. Via Noystoise:

"This is the latest set of NT(noystoise) series novelty synthesizers. following the overwhelming reception of the original NT01 series, it was pretty clear that if i build them, they will sell. the NT02 is simpler in many ways than the original NT01, but the sound and character are a bit more sophisticated than that of the NT01. the NT02 consists of a square wave VCO with chorus/delay, a white noise generator, a ramp LFO, and individual 12db resonant lowpass filters for the VCO and white noise generator. the pitch of the VCO is controlled by one axis of the VCO joystick, while the other axis controls the delay time of the chorus. the chorus circuit is basically just your typical PT2399 delay chip setup, except there is no feedback loop. the VCO is fed to the delay chip, and the delayed signal is recombined with the initial signal before the filter stage. the effect makes the VCO sound much bigger and warmer with the chorusing effect. almost like an old analog poly-synth with detuned VCOs. the white noise generator is your basic two transistor type found in many old synth designs. a common issue with the two transistor noise generators is that they require at least 9 to 10 volts to operate. that's just fine if you are using a plug in power supply, but when using a 9 volt battery, the noise generator usually wont work. in my case, the noise generator wouldn't sound with any less than 10 volts. however, the noise generator doesn't draw all that much current, so i simply used a 555 charge pump voltage multiplier to get the circuit where it needed to be. the problem i ran in to on the breadboard though, was there was some cross-talk from the 555 charge pump oscillator to the VCO, so i only used the 555 charge pump method for the first NT02(revA). for the others i simply buffered the VCO, and made a charge pump out of that. this way, if there was any cross-talk, it would be harmonized and unnoticeable. however, once the NT02 revA was built and working, the cross-talk was gone, so i guess it wasn't necessary. both the VCO and the white noise generator have their own respective filter with resonance control. the cutoff frequency of both filters are controlled by their respective axis on the VCF joystick. the center switch on the joystick toggles either the VCO or noise voice on or off depending on which joystick switch you press. each voice will remain on or off until the switch is pressed again. this feature was not included in the revA NT02. its voices are permanently on. the NT02's LFO is ramp shaped and can be set to modulate one of four parameters, or turned off. the LFO can modulate either the chorus delay time, VCO pitch, VCO filter cutoff, or the noise filter cutoff. on the revA NT02, the VCO pitch setting controls the maximum threshold of the pitch joystick, whereas the revB VCO pitch setting is independent of the pitch joystick. the LFO rate is controlled by the knob above the VCF joystick. the NT02 also has a volume knob, a 1/4 inch switching line out jack that bypasses the built in speaker when plugged in, and a center positive polarity protected DC jack that bypasses the internal battery when plugged in. the internal power supply is regulated, so any DC adapter between 9 and 18 volts will work just fine. unfortunately, unlike the NT01, the NT02 does not have CV inputs or outputs. the NT02 revA(black one) does have two 0-5 volt CV inputs for the VCO and LFO, but the revB models do not because their circuits' operating voltage is 8vdc instead of 5, which is kind of an unusual number... i would have liked to have scaled CV inputs that could turn 0-5 volt CV input to the necessary 1-8 volt CV input that the VCFs, VCO, and LFO require, but space was too limited. the inputs are in there though. i still kind of regret not including the ability to connect CV inputs to the NT02, but it is just safer this way. these were not intended as modular synths. they can be easily modified though, for any advanced users out there. hopefully these little synths do as well as the NT01 did so i can start on an NT03... the NT02s will be available at my for sale page until they are all gone. have a look, tell your friends about this BLOG!!!
Thanks for reading,
Tanner"
