Dubstep with the modular

Dubstep with the modular from Brandon Daniel on Vimeo.
"Dubstep track I'm working on, getting the big modular synth involved. The bass tone is actually Nord Modular G2, but being processed through the modular, drums are 808 + some other stuff... hopefully will finish the track in the next couple weeks."

Synth Fumbles... "Synthian Slips"

I did it again. I called and labeled the Yamaha CS01 a Casio. It's one of my most common synth fumbles. As much as I know it's a Yamaha, if I don't make the conscious association, I default to Casio. Obviously due to the look and size of the CS01. Another is the use of dashes for KORG and Yamaha in their model numbers. Yamaha does not use dashes, KORG does. It's CS01, not CS-01 and its MS-20, not MS20 for example. I know there are others, and you have caught me a number of times. I've been known to call the Micron and ION and vice versa for example. It's just the way it is... If you have any, feel free to share.

Roland Juno-106

via this auction

"Noise, filter and wave forms tested and working. All voice chips are working and have been properly calibrated. Internal battery for patch memory replaced. Original factory presets installed. Custom hardwood, japanese ash (tamo) end panels installed.

This Juno 106 has 3 of the chips replaced with 3 new clone chips produced by Jeroen Allaert (analogue renaissance)...

The Juno 106 is a great versatile polyphonic analog synth. The ease of use plus the ability to save your patches makes it a great all rounder especially for live gigs. The custom hardwood ends don't just look good, they provide added protection for the instrument. The raised height protects the sliders and front panel from damage in the event that the synth is dropped or knocked over. I can ship the original plastic ends if the buyer wants them."

Note this is the one from this video.

"Korg MS 500 SP Micro-preset CUSTOM WHITE monophonic synthesizer. A great gig instrument , very portable with a big analog sound. Very expressive and easy to dial in sounds. Best for bass. Limited , but a great sound very similar to the MS 20 ... not surprising since it contains the same filter chip... This one is in very good condition and has been re- veneered in white. This is the SP model with a built in speaker." See the bottom shot. See Korganalogue.net for resources including the manual and setting chart overlays."

Roland rs 505 paraphonic string synthesizer

YouTube via abertronic "Roland rs 505 paraphonic string synthesizer"


via this auction "Roland RS 505 , the ultimate analogue string synthesizer . Separate bass , synth section and of course strings give you a much wider palette of sound from which to create some wonderfully thick and rich classic analog sounds and very big bass sound! Comes with the fantastic sounding roland ensemble effect (stereo output) based on roland's dimension D chorus rack. External input enables you to plug in any instrument and use this great effect."

The Pulsar (Mini chip synth)

YouTube via StarfireMX
"So I've been busy working on this little home made synth, it's gotten to a point where it's doing enough to show you all. Here is the low down.

1. 16 step sequencer
3. LCD info screen
2. Saw and Square wave
3. Adjustable gate
4. Adjustable Tempo
5. Adjustable Tone
6. Switchable high pass and low pass filter.

Best part is I have a circuit board on it's way and it all fits on a board about 1.5 inch by 3.5 inch so very small!

Plan on adding a few more things.
1. Line out (Pretty much just a headphone out right now)
2. Saw works but a bit funky gotta fix the code.
3. Presets (I hope)
4. Indicator for what step you are on.
5. Adjustable filter
6. I have a version where you can set the gate individually for each note, but I just prefer the over all gate, might try to make it switchable but the code at the moment is glitchy.

Let me know your thoughts!!

Thanks!!!"
