Life's Window | Prophet 10 soundscape

video upload by MIDERA

"It was my Dad's birthday today. He didn't make it to this birthday, or the last 14 birthday's either. Time just goes on and takes everything away from us. But I wanted to write something on his Birthday. I miss him. I miss my mom too. I miss them both.

Meanwhile, I'm just barely hanging on. My wife still hasn't found a job and I sometimes think she won't get one before I lose mine due to all the awesome stuff going on in the federal government. We've been worried about what will happen when we're both without jobs. I couldn't get a job if I tried (and I have). I guess no one wants someone who has a really niche background. It's just not a great place to be.

Life goes on anyway.

"3 oscillator semi-modular synth, complex modulation capabilities, MIDI & CV control.

Probably no other monophonic analog synth has this amount of sound-bending capabilities at your fingertips on an ultra-compact footprint. Directly prepatched and switchable are:

VCO2 synchable to VCO1
VCO3 can modulate either VCO2 (only) or VCO1 + 2
VCO3 can modulate the filter
VCO3 can be taken out of the audio path completely, becoming an 'invisible' source for modulation only
the filter envelope (VCF) can modulare VCO2 ('sweep VCO')
VCF has two modes of keytracking
both LFOs can control VCOs AND filter cutoff at the same time and with independent settings
LFO1 can do S&H by sampling LFO2 (making them interdependent) or the noise generator
oh, there actually is an "OSC4" which is white noise (with its own level control), in addition to the white noise setting on VCO3 and the white noise setting on LFO2. That's 3 noise generators in just one synth.
glide function
VCA switchable positive / negative
envelope trigger switch
...
In addition, there are the patch points which add PWM modulation, external audio insert points, individual VCO outs, V-gate in on LFO1 +++

Condition:
Fully functional. Great overall cosmetic condition. Very few signs of use. A very few light marks – see photos."

"The FX Wizard goes into oscillation. I’m using the ARP just for converting patch cables to stereo and for grounding. It’s not powered. In post, I added a touch of reverb and delay.

Anyway, I hope you enjoy. Thanks."

"Limited Edition Polytik Modular Synths / Full Set in Boxes

Mint condition, Super Rare, Only 5 Sets were made. Considered a Modern Art piece.

POLYTIK is a collection of beautifully designed hand-held synth modules exploring the border between play and sound.

Born out of a DIY ethos and the maker community, Polytik has been crafted into something very different – a series of beautifully designed objects in their own right. POLYTIK uses open-source hardware and encourages users to make new modules and hacks.

The brainchild of and in collaboration with, these hybrid analogue/digital devices can produce a palette of sounds ranging from angular rhythmic sequences to abstract noise, pads and drones. "The Core module is loaded with 30 sequences (five discrete patterns per sequence) programmed by John Richards with interviews and comments embedded in the code from musicians and artists including: Jas Shaw (Simian Mobile Disco), Mark Fell, and Frieder Nake."

Specs:
• Created by John Richards (Dirty Electronics) and Jack Featherstone
• Very limited edition run of 5 sets
• The full set contains:
• Core (Blue) - A sequencer, programmer and mixer
• Combi (Black) Voltage-controlled feedback, voltage-controlled oscillator
• VCO (Red) Voltage-controlled oscillator (VCO) and voltage-controlled filter
• Noise (Yellow) Noise generator, patchable feedback networks and voltage-controlled filter"

"WORKING CONDITION: Good- All buttons, switches and sliders are intact and working well. All presets change and idnvidual volume controls for each instrument work and sound great. There are two small issues, though--- There is a low-frequency, low-level audio "hum" that is emitted regardless of the slider volume. Then there is a 16th note high frequency "tippy tap" sound that is a constant also, which changes speed in accord with the tempo slider. Almost like a click track going softly in the background. Neither of these sounds are off-putting in tone, and they are largely outdone by the pleasing sound of the drum tones. We suspect a re-capping of the power supply or some other simple service would handle these issues. It would be worth it, because this thing sounds great!"

8/24/25 Roland SBX-80 clocks a pair of Pasco Scientific 9301 + Yamaha EM-100 + Alesis MIDIVERB II

video upload by Cfpp0

"8/24/25 Roland SBX-80 clocks a pair of Pasco Scientific 9301 dual function generators + Yamaha EM-100 + Alesis MIDIVERB II

The Roland SBX-80 is set to 80 bpm, time base 1. The time base output is boosted by the right Pasco Scientific 9301 microphone preamplifier, then patched to the modulation inputs on both 9301s. The spring reverb is the internal tank from the Yamaha EM-100 mixing the two 9301s. A stereo reversed reverb from the Alesis MIDIVERB II creates the stereo echo."

Prophet-10, CP88 session | Receptor 2025-08-24 by atnr

video upload by atnr

"A piece created with Sequential Prophet-10, YAMAHA CP88, CLAVIA Nord Lead, and MOTIF-RACK ES. A session featuring delayed piano tones and synth sounds processed with spacious effects.

The Prophet-10 is connected to LOSSY, MOOD MKII, and blueSky — applying packet loss effects along with delay, pitch shifting, and reverb.

The CP88 is used to play electric piano sounds, with deep delay applied.

The backing track is provided by the Nord Lead and MOTIF-RACK ES, layering harmonies with synth pads. Reverb on the Nord Lead is processed through Specular Tempus."

Roland SH-5

Additional Nightlife Electronics Listings

"The Roland SH-5 is possibly the most feature rich vintage mono synth ever made by the legendary Japanese company. With 2 LFO's, 2 VCO's, 1 variable state VCF, 1 bandpass filter, 2 Envelopes, 1 VCA, S&H, Ring Mod and a simple but powerful switch matrix for routing modulation this synth is more than capable of making some of the most incredible tones and textures you can imagine!

Made in the late 1970's 'green face' Roland era, when their synths had a certain magic sound that is hard to describe. Fizzling and alive with electricity!

A handful of patch points on the back give you access to all the essential controls via CV so that this can play along nicely with a modern set-up.

This particular SH-5 has just been fully serviced in our Synthesizer Rejuvenation and Wellness Centre and comes with a 90 day warranty of good health. Original lid included."
