Fully Upgraded Roland MKS-70 with Retroactiv MPG-70
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
"The MKS-70 has every possible upgrade: Vecoven flash board with multiple banks of patch storage; professionally installed Vecoven PWM upgrade kit which puts this synth into Jupiter & CS-80 territory; Guy Wilkinson upgraded power supply which is WAY more efficient, stable, and runs much cooler; low noise cable routing mod; OLED display upgrade; and fresh battery. This already great synth is ready for the next 40 years, and runs circles around a stock unit! It's also loaded with dozens of stunning patch banks, including one that makes heavy use of the new PWM mod.
On top all that, the new version of Retroaktiv's MPG-70 programmer - the mk3 with optional patch storage upgrade. This is crucial because it gets around Roland's Patch/Tone storage limitations. And of course it gives you hands on control of every parameter AND it works as a universal MIDI controller for any synth or plugin!
All in, this whole bundle was over $4100 with parts & labor"

Yamaha CS-50 Synthesizer w/ 6-Voices & Aftertouch Mod

pics of the inside below.
"I bought a CS-50 years ago and modified it with a couple of extra cards to be a 6-voice. It is serial number 1031 which is the earliest unit I know of. The rails were actually drilled for six voice cards from the factory; I expect they intended the CS-50 to be a 6-voice and later backed off to four voices. The two additional voice make it much more musically useful IMO.
The new voice cards are original CS cards that were plumbed into the SH and KAS boards with the required modifications on those boards to make it happen. The wire looms were made by hand using Yamaha wiring and all the correct color-codes (of course) which match the coding in the CS-60. It's a very professional job using wax-coated lacing for the harnesses.
The voice boards have been modified to include LEDs which illuminate when the card is activated for ease of maintenance. All circuit boards have been fully recapped. The power supply has been fully-reworked with a new power cord, all-new capacitors, rectifiers, opamps and all power transistors on both the circuit board and the heat sink.
It has also been modified to have Sustain pedal function like the CS-60 and CS-80. I did not add an On/Off switch on the panel as on the later units, rather all the switching is done internally when a Yamaha sustain pedal (or other NC pedal) is plugged into the added socket on the back panel.
It includes the lid, but there are no legs. The metal box that contains the power cord when it is stuffed up inside the synth is missing. There are some scratches on the left modulation panel and right power switch panel, but the main panel is in pretty good shape.
Another modification I did was to re-route the aftertouch volume Level paddle to instead control the LFO Speed. I find it much more expressive that way, but I can easily put this back to normal operation if a buyer would like to have that modification removed. The unit has been completely calibrated and is ready to go."

AXON-1 & 2 Expanders - Basics
video upload by ALM TV
"The AXON-1 & 2 provide Pamela’s PRO Workout, SQUID SALMPLE, and MFX with four additional freely assignable CV inputs. The AXON-2 additionally provides manual offset controls with each CV input along with two performance buttons that can be mapped to various functions depending on the host module.
The AXONs function in a similar way with all three of the host modules with only one AXON supported per host at any time. Here we take a look at using both AXON-1 and 2 primarily connected to the Pamela's PRO Workout."
