STS wave multiplier as sound source

YouTube Uploaded by DrOctave1 on Sep 7, 2011

"Useing the bottom wave mult as a sound source. Modulated by a pvco going into a variable bandwidth vcf . the clock for this is comeing from the dtg that also is cving the wave mult and the filter vcbw and vcf inputs. blah blah just listen dif textures no reverb or delay."

Bug Accordion

"Best of CGS "SWAMP" Sequencer playing w/ the BugBrand System. Dual BugBrand LFO's playing against each other - while clocking the Sequencer. Timbre of the E350 controlled by the 4x8 main sequence . . . while the melody/transposing is via the gated comparator/mini seq. The timing is subdivided via the Bug"Division" module. Then main output is fed back into itself through VCA control of PT Delay module. Finally a bit-o-reverb from the T-Resonator."

MATRIXSYNTH-P

Update: it looks like there is enough interest for MATRIXSYNTH-P to launch. If anyone is interested in a post, send email to matrixsynthp@gmail.com. Note anyone is welcome to post including dealers and manufacturers. Remember, P is extra and does not change anything on M, B, or C. They will continue on as usual.

Original post:
Quick question: Is anyone interested in a paid listing site? Currently M is about synth spotting, B is auction overflow, and C is music from readers of the site. P would be a paid listings site for private items for sale, upcoming gigs, or for promoting/posting whatever you want for that matter. It would be very similar in format to M, B and C with some key differences. Aside from being a paid listings site, the right would be dedicated to premium listings, and there would be a header section on top to filter by category. You can see an empty template here: MATRIXSYNTH-P. How much would a post cost? $3 per post and $5 for a premium post which would also get placement on the right of the site and go up on MATRIXSYNTH Twitter and Facebook. All posts will go up in a section on the top right of M, B, and C. This could change to premium posts only depending on how much goes up. Why charge for it? I'm busy enough on M, B and C. P would be extra and I think people could find it useful in selling items, putting up want ads, and promoting gigs and other things. And of course it helps support the time it takes to run all sites. Note, M, B and C would remain the same and posts on P could make it to M, B or C if they meet the criteria. Also posts previously featured on M could be re-posted on P if paid for. If you think you might be interested in using the new site's services please vote.




To post on P you would submit the following for review to matrixsynthp@gmail.com:

1. Title: Title you want for your post.
2. Body: Text you want in the body of the post.
3. Media: images or links to video and/or audio (you will need to host them yourself on SoundCloud, YouTube, Vimeo or other). Images can be hosted on P and videos and audio can be embedded using any of the services mentioned.
4. email contact info if necessary (for items for sale). The email alias (not the full address) can be used as a label for the post. This will allow sellers to build a reputation and allow buyers to filter posts by sellers to review feedback left in comments.

Note listings would be similar to Criagslist in that they are 100% between the buyer and seller. MATRIXSYNTH assumes no responsibility and cannot vouch for either the buyer or seller. The site will be a simple paid listings site. However, you will be able to review and leave comments in posts and you will be able to filter by seller alias labels. Of course any bad seller can just create a new alias and email address, but this would be the same on other sites.

Although you can submit anything for a post, there will be a bar including no hate, discrimination, illegal file sharing and the like. The bar will be pretty open to start though, as it would be interesting to see what sort of things come in. The best way to find out if it meets the bar is to send it in. If you have something you want to go up now, by all means, do send it in. It just takes one post to get it started and you could be the first.

"The Korg iMS-20 is a great synth for the Apple iPad. This video shows how to control this synth with a guitar by using the Sonuus i2M musicport.
The Sonuus i2M musicport converts guitars and other musical instruments to MIDI with very low latency. Being a standard USB MIDI device, it works with the iPad using the iPad camera connection kit."

Unlocking Yamaha E70 organ into Yamaha CS80 synthesizer

YouTube Uploaded by allvek597 on Sep 5, 2011
Re-Published on Feb 12, 2016

Update via e man in the comments: "There is no CS style VCO, it's just the VCF's and VCA's - the VCO's in the electronic design are what's used to clock the waveform data from the basic waveforms in ROM. It's like the Korg DW series, only analog on the VCF/VCA side. It has very little pitch control other than minimal glide (semitone range) and same for the vibrato (if even)... the source oscillators are purely phase locked digital constructs."

And: "There is no analog VCO in this entire synth, certainly nothing resembling the CS80 or any other CS synth - zip, nada, zilch - anyone telling you otherwise is trying to sell you swamp water. This is a giant polyphonic that has much more in common with the Korg DW series (also having crude basic waveform in rom), but very much lacking in it's ability to do any pitch control - what little there is, is a an digital approximation of minimal range. The only place you could add modulation circuitry to any great effect is the VCF and VCA section of the Orchestra Voices - pitch modulation is either limited global vibrato or equally minimal vibrato on the upper manual via wiggling the keyboard that drives a photovoltaic shutter combo, again going to a digital interface having little effect - even the glide is minimal and digital. You will never get anything properly analog out of the the Wavetable oscillator end as it's a giant digital construct with loads of sample and holds to distribute the wavetable rom voltages that approximate the basic synth waveforms (ramp, pulse, square). It's basically 3 waveform samples in ROM with very little control over pitch other than basic notes (the speed that the sample is read out from the ROM)."


The following is the original post starting with the video description:

"Mystery is resolved. Chopped and completely electronically modified analog Yamaha E70 organ into Yamaha CS80 synthesizer. What You see now is 2 fully programmable polyphonic synths 2 OSC's per voice + fully programmable 2 OCS's per voice monophonic synth in a body of Yamaha E70. Same P.A.S.S sound technology, same analog filters and same sound, same offspring of legendary Yamaha GX1.
Any questions, please visit www.alvek.us"


via this auction

"Here's one more organ from my collection: Yamaha E70 . What You see in the pictures is completely modified Yamaha E70 in body and electronically. Organ after chop work went 327lbs down to 130-140lbs(Yamaha CS80 is 242lbs) and under the hood all electronic carts are located pretty close to like inside of CS80. It's been a while people talking about E70 which has same P.A.S.S technology like CS80 and electronic carts, all wiring are practically the same like CS80. Yes, E70 has absolutely the same analog filters like CS80, same sound synthes and it does sound like CS80. This particular E70 has beed modified from organ into 2 and half fully programmable CS80. All presets still have same functions except FUNNYII preset green buttons. Those 3 green buttons(1 for upper, 1 for lower keyboard, 1 for pedal board or extra keyboard) function now differently. When You push FUNNY II E70 starts to work as most powerful and expensive programmable synth-Yamaha CS80. On left top of organ You see control box. The box has 3 sections: 1st for upper keyboard, 2nd for lower keyboard, 3rd for footpedal/or extra keyboard you can hook up. You can see all signs under the switches(3 waves forms sawtooth and 2 square waveshapes) and pots, they have same function like on CS80. So after all this E70 has 2 polyphonic 7 voices 2 OCSs per voice CS80 synths and one monophonic 2 OCS per note synth (pedal or extra keyboard which can be connected to E70 is monophonic, it's perfect for bass lines and pretty good even for leads as far as You will move 2 OCS slider from 16' up to 4'). Oscilators can be detunes between each other and between keyboard. Does E70 sound like CS80?. Yes, it does. Main different between E70 and CS80: no velocity and aftertouch on E70. Big flaw. On another hand You have 2 and half CS80 under the hood. You can build sound on upper keyboard and MIX IT with sound you built on lower keyboard. Also you can add organ/orchestral section(they all can be saved in memory-see small control panel on a botton of organ to left-very much the same look like on CS80) from upper keyboard AND organ/orchestral section from lower keyboard. Same thing can be done between lower polyphonic and monophonic keyboard/pedals: monosynth also can be played on first 2 octave of lower keyboard. Now You realize CS80 is kind of kind of behind! PLUS very powerful arpeggiator! and even cheesy drum machine and 100 lbs less. From control box You can see 3 cables coming inside of E70, each cable has 25 pins . The connector 9 pins in a middle of a back of E70 serves expression pedal. 3 inputs 1/4 on back are not hooked up. Could be 1/4main output(original main output on a bottom of organ)or sustain pedals-it's easy to hook up. Same about 6 inputs on control panel-they are not hooked up. It's your choice how to use them. I didn't connected any inputs for 1/4 jack, coz basically all extra functions are on control panel of organ. I don't play on stage, so I can turn on sustain effect simply by hand. The organ is absolutely stable in tune and doen't have overheat problems like CS80 Anyway, if you are still skeptical about what You read here, please check some INFO on line about unlocking Yamaha E70 and Yamaha CS80 both children of Yamaha GX1. And don't forget how much money you will save not buying CS80. Please check, read and watch all links below and You will see it's not a dream anymore. You can get 2 and half CS80 more than 4 times cheaper... compare to ebay price for last month. "
