GS e7 - Analog Poly Synth with Ladder Filter | Full Track

video upload by Mamotreco

"Music track made fully with the GS Music e7 polyphonic analog synthesizer from Argentina. All sounds apart from drums are made with the e7, multitracked in Ableton Live 11. I originally composed the song with a VST synth, but subsequently rerecorded all the midi tracks with the E7 from scratch.

I received the synth earlier this week and recorded the track fairly quickly - I've since had time to create nicer sounding patches which I look forward to using in future tracks.

Yamaha DX7 – Legendary electronic music, Jean Michael Jarre Oxygene and Vangelis Blade Runner Blues

Published on Feb 9, 2018 Power DX7

"This is a Yamaha DX7 music video of re-creating those legendary electronic music by two legendary musicians and composers, Jean Michael Jarre and Vangelis.

Jean Michael Jarre - Oxygene Part 2 (short version) – I created a short demo of the famous electronic music with a lot of analog synthesizers used in the original score. I used the DX7 MK1 to re-create analog bells, percussive sound, metallic sound and pitch bending sound. The original score also features a beautiful analog strings/pad sound, and I created the DX7 version that is equally beautiful. There is also another beautiful pad that used for a release sound for the saw percussive sound. What I love the most is the amazingly beautiful analog pad (I’m a sucker for beautiful pads/ strings). That is the reason why I love Oxygene Part 2, as it features this beautiful pad/ strings.

Vangelis - Blade Runner Blues (Full Length) – This project of re-creating this beautiful music/ sound track from the original (and the best) Blade Runner started by great friends of mine asking me about Yamaha CS-80 type lead sounds. Once I remembered that beautiful sound track in Blade Runner (watched many years ago), I decided to challenge myself to re-create the whole music using only the DX7 MK1. It took me many months of tweaking DX7 patches, listening to the sound track, transcribing music to Logic Pro X, recording many takes and mastering for the final version.

It features the famous Yamaha CS-80 lead, another great Yamaha CS-80 harmonic rich and gritty saw type pad (I just love pads and strings!), Yamaha GS-1 vibe, and a window rattler bass.
For viewing enjoyment, I put photos of city night scenes taken in the city of Melbourne in Australia (what a beautiful city with full of interesting features).

By re-creating those legendary electronic music, the DX7 proves itself that it’s an amazingly capable and versatile synthesizer (and really great at producing beautiful pads!!!).

So relax and enjoy the legendary electronic/ synthesizer music re-created by Yamaha DX7 MK1.

Note: All the DX7 sounds are Power DX7 original patches created using the DX7 MK1 only (no editor). Effects including reverb, chorus, flanger and delay are used for some patches. No equalizers are used for all of the DX7 patche."

Custom patches for GS-e7 by synth_nyc (FREE download)

video upload by GS Music

"We proudly present these 64 custom patches for the GS-e7 Analog Polyphonic Synthesizer. The patches were made by synth_nyc and are now available to download from our website for free. In the future, they will be incorporated as factory presets."

"A few words from synth_nyc:
After designing some custom patches for Black Corporation Japan and GForce Software Ltd, I chose to design patches for the e7 because:

1. It sounds great to my ears and offer a complementary tone to all my hardware and software synth 2. It has memory
3. It has full MIDI implementation of all parameters, so I can remote edit it.

In addition; the e7 has some unique features, as far as I can tell, which really make it shine:
* Stereo output / voice spread with pan modulation
* 3 LFOs that can modulate pitch, PW, VCF and VCA
* Very cleverly / musically implemented features such as A/R velocity modulation, envelop KB tracking modulation, LFO rate KB tracking modulation, etc...

Not to say that the discrete VCO, VCF and VCA are a winning combo for a true analog tone.

Please contact GS Music if you need support.

Enjoy!

Mini-bio
synth_nyc first synth was a DX7 (mk1) in the mid-80s. synth_nyc always enjoyed programming sounds on the machine and it never appeared complex or non-intuitive to him. synth_nyc first analog synth was a MKS-50 (with PG-300) where he discovered that you did not need to spend 4 hours to design a great patch! After that, synth_nyc is grateful to have own classic and unique machines from the late 70s to early 90s like a CS-80, a Waldorf Wave, a PPG Wave 2.3, a MemoryMoog LAMM, Prophet 5 Rev2, Rev 3.3 and Prophet VS, OSCar, OB-X, Synthex, Sunsyn, Jupiter-8, Chroma, Hartmann Neuron and Voyetra Eight (the only vintage synth_nyc still owns) and many more! synth_nyc has learnt and enjoyed programming them all. Today synth_nyc is focussing his time on programming analogue renaissance hardware synths -with memories-; as well as new hybrids and new digitals, but also software synths as emulations, virtual modeling have come a long way; especially in the past year or 2 (so have computers) and are letting us enjoy amazing machines for a reasonable price, so close (or better) to the originals and hassle free."

GS Music GS-e7 7-voice Analog Polysynth

video upload by GS Music

You can find additional demos and pics of the GS-e7 in previous posts here.

Available in Blue, Red, and Black.

"We would like to introduce our new Analog Polyphonic Synthesizer, e7. It is a 7-voice, 4-part multitimbral desktop synthesizer, also featuring MIDI polyphonic expression (MPE). This instrument is the result of years of research and development to come up with the first analog polyphonic synthesizer ever made in Argentina.

Signal path
The signal path is completely analog, featuring two VCO per voice, a white noise source, a mixer, a 4-pole low pass VCF and a VCA. The control voltages are digitally generated, including 3 LFO, 2 ADSR-type envelope generators. Finally, it has a stereo digital effects processor with Delay and Chorus. LFO 1, LFO2 and the delay can be synced with the MIDI clock using a user selectable subdivision.

Oscillators
It features two VCO plus sub oscillator per voice. Each oscillator has 3 different waveforms: triangle, sawtooth and saw-tri (triangle+sawtooth). There is a fine-tuning adjustment and a transpose option, allowing tune adjustment up to +/- 2 octaves. Tuning can also be modulated with any of the three LFOs and EG1.
Furthermore, each oscillator has a pulse wave that can be turned on or off, which is mixed with the other waveforms. Its pulse width can be modulated with LFO1 and/or EG1. Oscillators can be hard synced.
The autotuning algorithm takes about 2 seconds to complete. All the voices are tuned in parallel, making a lot faster than usual.

Mixer
The mixer can control the levels and mix the two oscillators, the suboscillators and the white noise or the external input.

Filter
The filter is a 4-pole ladder-type low-pass filter with resonance control. It can be modulated with EG1, this modulation an also be affected by velocity. It can also be modulated with any of the 3 LFOs. On the other hand, it features keyboard tracking and it can be controlled by the modulation wheel or aftertouch.

Chorus
There are two types of chorus available: basic and ensemble. The Basic algorithm is subtle and allows you to add some spatiality tothe resulting sound, while the Ensemble algorithm adds a different dimension to the sound, simulating a string or vocal ensemble. The Basic algorithm uses two delay lines, while the Ensemble uses 4 delay lines. Each delay line has its own internal LFO. There are controls for rate, depth and mix.

Delay
The delay can be a stereo delay or a ping pong delay, with its maximum delay time being as long as 1.35s. It is possible to sync the delay to the MIDI clock too. If the delay is synced, the delay time knob controls the time division instead of the delay time. There are controls for the feedback and mix too.

LFOs
There are three LFOs available. LFO 1 and 2 have 5 waveshapes: triangle, ramp up, ramp down, square and random with sample and hold. LFO 3 has the first 4 waveforms and is activated with the modulation wheel and/or aftertouch.
LFO frequencies go from 0.1Hz to 100Hz. Additionally, LFO 1 and 2 have different modes:
Monophonic: The LFO is in phase for all of the voices.
Polyphonic: The LFO is generated to a slightly different frequency for all of the keys pressed. This allows an interaction of the phases, generating more complex modulations.
Keyboard Tracking (KB Tracking): The LFO frequency varies according to the note played following the chromatic scale.
Keyboard Sync (KB Sync): The LFO is restarted when a key is pressed. Each voice has its independent LFO.
Clock Sync: The frequency of the LFO is synced to the MIDI clock signal. The e7 automatically detects the BPM of the clock signal. It can be configured to generate different rhythmic figures.
Keyboard + Clock Sync: The LFO frequency will be a sub-division of the MIDI clock signal. Also, the LFO will be restarted each time a key is pressed.

Envelope generators
There are two ADSR-type envelope generators. There are controls for attack, decay, sustain and release. Attack and release can be modified by velocity and the envelope times have keyboard tracking.

Stereo
By default, the voices have a stereo panning from left to right. By adjusting the stereo spread, it is possible to set all voices to the center or set them from right to left. There is also a stereo motion option that allows this stereo spread to be adjusted by an LFO.

Presets
The synth can store up to 640 presets, 128 of them being multitimbral presets.

Multitimbral
The synth can have up to 4 multitimbral parts. Each part has it complete sound configuration, assignable MIDI channel, keyboard zone, velocity zone, transpose setting and MIDI filter. Additionally, each part can have different voice assignments and/or share some voices.

MIDI Polyphonic expression
MIDI Polyphonic expression is supported by the GS-e7. It was tested using GeoShred, allowing independent pitch control and cutoff for each voice."
