"Rare and interesting physical modeling rackmounted synthesizer. We did some very minor servicing and thoroughly tested and played this unit and everything appears to be working as it should. Please check with us before attempting to buy it to make sure it's still available as we originally bought it for our studio and may have changed our mind about selling it if it doesn't sell fast."

"This unit has been fully serviced to make it better than the rest, a process that cost us 22 hours of highly skilled and valuable tech time. The result is a professionally overhauled instrument that's fully functioning and is ready to play, unlike most, and is justifiably more costly than lesser examples. Depeche Mode used this model sampler heavily to create its signature sound in the 80s.
Our tech did the following work to this item:
Fuse holder replaced.
2 molex connectors terminals were replaced.
Memory tested, all tests passed.
Front panel membrane sheets removed and replaced.
Power supply recapped.
Replaced defective floppy drive with a serviced one.
Replaced 1/4” jack nuts and washers.
Cleaned key contacts.
Replaced backlight with new one.
Multiple burn in tests performed, all tests passed.
Note: These originally left the factory with 6 rubber feet. The one that would normally be found in the back left corner is missing, but thanks to the 5 others, this is a non-issue as it's perfectly stable the way it is. We normally would have just replaced it, but this isn't the fast and easy process it is on most other gear. We can pay our tech to do it though if it matters to you - please contact us for a quote.
This EII is the PLUS version, with maximum memory (17.6 seconds max sampling time)."

"The Frostwave resonator is a clone of the filter in the Korg MS20.
Australian pedal , and highly regarded.
It screams."

Another rendition of Corridors of Time, using a new PiMT32
video upload by MIDI IN
"This video is for embedding in the product listing for my new Pi HAT which you can see in the video. I designed it to be the way that I wanted - with he 2-button/rotary encoder configuration, just MIDI in and a cover plate to neaten things off.
I'm a little unclear about the authorship of Corridors of Time, I believed it was composed by Autumn Altair (the source of the MIDI that I'm playing here) since it appears on Echoes on Stone Walls which I believed to be original compositions. But I see that it may be by Yasunori Mitsuda. Either way it's beautiful."

"Kloob - Dark Solstice Echo
A friend of mine lent me the Nord Micro Modular synth, and I'm pretty surprised by its sound — and I still have to dig into the software editor!
All sounds come from hardware synths:
Nord Micro Modular: baasline sequence (midi channel 3).
Micromonsta 2 sounds: pad-drone sequence (midi channel 2) and ‘Sad Pad’ (midi channel 1) played in realtime.
Sonicware Live Ambient 0: sequencer and noise sound in layer 4.
Behringer Edge: Bass-Drum loop.
Hologram Microcosm feeding the ‘Dreamy Pad’.
Hope you like it!
Thanks for support my music!
Cheers,
Dani

Mood Machine | Sonicware Liven Evoke | New Set of 14 Songs
video upload by Sonic Cartography
"Track list and lots of notes below:
0:00 - 1. Dream Machine - With the Sonicware Liven Evoke, I’ve often been playing songs live, without using the sequencer, which I used for almost all of my songs with the Liven Ambient Ø (the two sequencers are very similar). With this song, I use the hold feature to hold some notes of textural sound in a couple of layers, while playing the piano layer live. The piano sound morphs between an acoustic and electronic sound a little bit after I play each note. Around the halfway point, with the chromatic pitch shifting, everything starts to turn into a granular storm (there are no granular effects prior to this), which is helped by the fact that you can cut the dry signal of each track and have a 100% wet mix of the reverb and/or granular sound. Oh, also, I want to give a thank you/shoutout to this video by @BenLevin because I started messing around with the chords that led to this song after watching it: • The secret to EMOTIONAL chords . His channel is one of my favorite music education channels on YouTube, so do check it out!
