Yamaha ED20 Sample Pack Demo - Lovingly recorded from a rare drum pad synthesizer

video upload by Edward Jones

"You can buy a sample pack of all sounds recorded dry and lowest pitch from the unit. The samples are possibly 12 bit internally. I cannot work out how to open up the machine without destroying it (hence that small tear on the drum head)/

https://loscha.bandcamp.com/album/yam...



Each sample has been normalized. The actual sample playback volumes on the machine were erratic. They were triggered using the PAD IN terminal at the back and triggered from the DAW so the samples would be time aligned and sightly easier to chop."

Wait for it.

"I forgot to adjust the tiny trimmer inside the unit! D'Oh!
Upon reflection, it is probably a drive control, as the knob on front panel just adds in the volume of the distorted sound, not the quality of the distortion."

ChucK (1.5.0.0; codename "chai") Update

This one is in via supporting member, Loscha, who had the following to say:

"A new major release of audio programming language ChucK has come out.
ChucK has been on the scene for a solid 20 years now.
Apart from general synthesis and analysis, ChucK was a big mover in the early Live Coding music scene.
The language lets you add instruments and algorithmic elements to a live performance at will.
ChucK is a very easy and powerful language to learn."

The following was made in ChucK by Loscha back in 2018. You can find the code at the bottom of this link.

Loscha Opens up a Pollard Syndrum Quad!

video upload by Edward Jones

"This is going to be a long restoration!

The drum triggers go into the unit on a five pin Latched XLR, not a DIN as I said in the video.

The power supply is in an external box that has a mains transformer, and a voltage regulator, only to have it regulated again inside.
twice.

The MM5837 appears to be a no gp (I have a spare) but the real issue is that the faders and switches are all corroded and jumpy.

I did end up taking the panel board off, and the faders seem to be like the contemporary ARP kind. Plastic body, moving wiper body."

JVC & Lowrey Keyboards KB-500 KB-700 Micro Genie

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

Note these are from supporting member, Loscha.

The are listed for parts. Note the smokey transparent music stands, that also act as front panel covers when not in use, on each of them.

"Of Note: all of these keyboards have the smoke grey plastic music stands, and they don't have the tabs broken off!!!!! These are quite rare in any condition as they fall off if you carry the keyboard at an awkward angle, and can shatter.

Despite my vague notes here about the keyboards partial functionality, the only one I can be sure of is that the KB-700 actually was making good noise, accompaniment played, voices switched, etc.

Updated to add: the winner of the auction will receive the KB-500 service manual via email. I had to purchase this separately.

NO RETURNS ACCEPTED -- THESE ARE SOLD AS IS, AS STANDING.
JVC KB-500 White Keys - no sound, doesn't power up
JVC KB-500 Black Case Silver Keys - no sound, doesn't power up
JVC KB-700 - this one works except for tempo slider.
Lowrey Micro Genie V-120 "Mach Plus" (rebadged JVC KB-700) only a few keys worked a few times, I think the drums worked however
Lowrey Micro Genie V-105 with MIDI - doesn't turn on at all. Has a cute little cartridge that stores the accompaniment patterns.

These are collection ONLY from Neill St Carlton, Melbourne, Australia."

Loscha presses Play: Yamaha PSS-270 Demo 𝓑𝓲𝓵𝓵𝔂 𝓙𝓸𝓮𝓵 𝓙𝓾𝓼𝓽 𝓣𝓱𝓮 𝓦𝓪𝔂 𝓨𝓸𝓾 𝓐𝓻𝓮 has VERY weird instruments

video upload by Edward Jones

"The Yamaha PSS-270 is from the FM Synthesis line of keyboards.
The audio generation is handled by the YM2413 OPLL chip.
The OPLL is very well documented. Please look here for more information - https://www.smspower.org/Development/...
This chip has direct audio out, no DAC required.
One output is the Main voice out, and the other is the Percussion out.
On this unit, the Percussion and Main are both routed through the chorus unit. The chrous is MN3102 and MN3206, controlled by a fixed LFO. There is no feedback on the chorus. This could be added for a much more flangier effect."

"Today we have a scan from my paper book archives.; Electronic Musical Projects by P K Sood, published by the Business Promotion Bureau of India - a company still producing educational material for IT.

These books were reasonably common in Australian Electronics Parts stores in the early 2000s. They were cheap, and there were several in the series.

Today I present Electronic Musical Projects, but I also have Practical Timer Projects, 555 Timer and its Applications and 41 Projects Using 741 I.C.

These books, particularly the musical one, has an almost Zine feeling to them. They're crooked, the schematics are lovingly hand drawn.

I have never built any of these musical instrument projects,

A previous scan of this books exists, but, it is unusable"
