"Roland SH-5 analog synthesizer demo showcasing S&H, envelope retriggering and bandpass filter tweaking.
The Roland SH-5 is an iconic and rare vintage monophonic synthesizer that was manufactured from 1976-1981. It features 2 VCOs (32' to 2' with triangle, saw, square and pulse waveforms), 2 LFOs (LFO1 = saw, reverse saw; LFO2 = triangle, sine, square) and 1 S&H with sample time & delay time.
The Roland SH 5 has 2 VCF filters: 1 multimode LP/BP/HP and 1 Bandpass, both with cutoff and resonance. 2 Envelopes (1 AR and 1ADSR) can be routed to filter, osc and amp, and there is env sensitivity and keyboard tracking on the filter. On the back of the SH-5 are various inputs/outputs for CV and other control.
Additional features include portamento, pitch bend, ring modulation, soft & hard sync, white & pink noise, external audio input, VCA panning, VCA-triggering via S&H, LFO2 or external trigger. A comprehensive Mixer section allows for routing of 5 audio signals through VCF, VCF+BPF, BPF, or direct to VCA.
The Roland SH-5 is a classic vintage synthesizer that can output massive bass, piercing resonance, create amazing textures/noise/FX, and of course leads and other standard tones. The additional bandpass filter is also a key feature that sets the Roland SH-5 apart from many other synths in terms of tone."
Ploytec has launched the PL2 Logos prototype board on Kickstarter here. You can find two previous videos below this post in the archives here.
"At Superbooth19 in Berlin we showed a sample of the PL2 Logos prototype board. This PCB makes it a lot easier to translate English text to the allophones needed for Ploytec PL2 based speech synthesis (which is CTS256-AL2 / SP0256-AL2 emulation).
On the board, a PL2 synthesizer is already integrated, so there's no need for a separate PL2 (though it's always good to have some of those).
The included USB keyboard allows entering text, and to store / recall text from memory using function keys. Each function key can hold up to 39 letters in up to six rows.
Via the integrated USB MIDI it's possible to capture and playback the MIDI notes triggering the words. On top, you can record the many MIDI notes representing allophones, to a DAW.
Please note: The knob will be most likely missing on the final board, as it never had any functionality and is not necessary for operation.
Risks and challenges
As the technology is basically working, the task to be done is bug fixing, creating firmware update functionality, changing the PCB to potentially fit into an existing case (not included!) and getting a bunch of PCBs manufactured."
"These patches are the result of a week with my newest synth, the Moog One. It's a wildly powerful synthesizer, the most powerful polysynth I've ever encountered. I can't wait to get to know it better!"
"Buchla Easel Clone rev 1. It is powered and housed in a Zero Halliburton case. It was repurposed from a former photographer and you can see some notes on the inside of the top case. The wiring for the case has not been finished or started. It is a larger case with the idea that you could put 1-200 module next to the 218r (again not finished). The Easel itself (218r 208r) is powered. The IEC power cable comes out the back. The Synth sounds fantastic and is very much alive. The bass is insane! Reverb is dark... I like the "swampy" sound of the rev 1. This was supposedly built by Roman but I can't prove that. FULL DISCLOSURE --- Other things to note, all of the sequencer notes light up but the step it is on lights up brighter. Tracking over 3 octaves can sometimes go out of tune (probably would benefit a calibration but it is not necessary). Sometimes the pulsar does not trigger when you self trigger it (this is a known issue with some REV 1). Includes Pomona Cables and Banana short plugs. Everything you need to get started."
"Not to be confused with the standard Emulator II, the II+ HD includes a built in 20MB hard drive allowing for a longer sampling time than the standard model.
This unit was just serviced by our in-house technician, it was fully re-capped and inspected."
