Busy Basics - Building Basslines
video upload by ALM TV
"Creating a simple bass line is great starting point for learning the fundamental elements of patching a modular synth. In this video tutorial, we take it one step at a time, starting with building the bass voice itself, then sequencing it from a MIDI keyboard.
SECTION TIME STAMPS:
00:00 - Intro
00:29 - Oscillator
01:38 - Filter
02:49 - Envelope
05:22 - VCA
07:47 - Sequencing
Thanks for watching!"
Busy Basics - Building Basslines - PART II
video upload by ALM TV
"In this second part of Building Basslines, we expand on the original patch from part I, taking a step by step look at a few more advanced techniques to add personality and greater functionality to the patch. This includes using pulse width modulation to add movement, mixing oscillator waves for a thicker sound, adding a second envelope for greater control, and sequencing from within the system using Pamela’s NEW Workout.
SECTION TIME STAMPS:
00:00 - Intro
00:33 - Pulse Width Modulation
01:50 - Mixing Waves
03:15 - Using Two Envelopes
05:39 - Internal Sequencing"

"Original vintage aluminum panel with the Oberheim logo. It is in beautiful cosmetic condition. This is exactly the size of a SEM panel and was taken from an Oberheim Two Voice which only had one voice fitted and this panel. I am not including the power supply and the Oberheim case in the third picture. This is a picture to provide context on the size of the panel for sale."

"To me this sounds better than most late 70s minimoogs Ive used and you can save 256 patches on this! This Source is the one you want and will save you a TON of headache in the future. This source has been serviced in 2021 by the best in the business right now, Rosen Sound, and sounds absolutely fantastic. The fine folks at Rosen sound rebuilt the power supply to help future proof the rest of the components and increase stability. They also installed a new Encore Midi which adds midi sync ability, midi in and out, and expands the memory 16 times the original, these are 325 new plus installation. Please research the encore midi system before purchasing. They also replaced the two light sensors for the control knob with NOS parts and calibrated to factory specs. These all will go and these parts are getting harder to find, like damn near impossible, and very hard to install/calibrate. It took Rosen Sound months to source these parts alone and they probably own the last remaining available for these. This control knob is now ready for another 30 years of use and this synth is impossible to control without it. As it is the membrane works perfectly but it also comes with a spare membrane panel from which is supposed to be the best replace panel available for when the membrane experiences problems in the future (they all go bad eventually). Parts and labor for all of this future proofing on a once very finicky synth was about 1500 dollars. If you buy a different source and want to keep it alive I would expect to pay the same in the near future."
