Giorgio Robino Yamaha DX7II 393 original patches collection
Exploring FM soundscapes is an inner trance around the consciousness

An introduction about my synth programming modus operandi

All the patches are Yamaha DX7IIFD original patches programmed by myself in the past years, between 1993 and 1996. I spent so many nights working with the synth and an old Mac patch editor; I do not remember exactly but surely I spent almost tree hundred days of my life. All the sounds come almost completely from the synthesizer sound exploring trips. Sometime I started a sound using an existing patch (download from internet or gave to me by friends), modifying the soundscape time by time, but in many cases I start from scratch (status zero), also using some controlled random features of the computer editor.

About the kind of sounds

When exploring soundscapes with DX7II years ago, my target is to reach very slow-motion evolving sounds, but all my work is imperfect in this way. In true, only sometime in these patches I have achieved what I had in mind. The soundscapes I truly love are sounds with very low attach and release with smooth tonal evolving/morphing. Just in these times I discovered musicians like Robert Rich that have implemented these slow-motion evolving music at artistry levels.

All the sysex patches are composed by a DX7II "bundle" of 3 banks: a performance bank (32 performances), a voice bank (64 voices), an internal microtuning banks (2 sets). I collected all my work in 15 bundles, here below named and detailed; all the performance names and some notes are detailed in a description text file (.txt), associated with the sysex file (.syx):

     bank 01: alienazi.syx, 32 patches, very psichedelich\dark ambient sounds

        Download for FREE alienazi.zip, a DX7II PERFORMANCE BANK: alienazi.zip

     bank 02: allucinazioni.syx, 30 patches, slow-motion, very psichedelich\dark ambient sounds
     bank 03: analogia.syx, 32 patches, analogic\power synth emulations '70 like
     bank 04: archettiestringhe.syx, acoustic and electronic strings emulations, 17 patches
     bank 05: bassissimi.syx, acoustic and electric bass emulation, 28 patches
     bank 06: brassonerie.syx, acoustic and keyboard-like brass, 25 patches
     bank 07: cordemultietniche.syx, stranges plucked strings, 31 patches
     bank 08: drummatica.syx, psichedelic percussions, 22 patches
     bank 09: infinitasprimordiali.syx, slow-motion electronic pads, 32 patches
     bank 10: orgiaorgani.syx, organ emulations, 32 patches
     bank 11: percussionidanzanti.syx, stanges ethnic percussions, 32 patches  
     bank 12: rimarginazione.syx, strange pads, 6 patches
     bank 13: sinteticaextasy.syx, slow-motion analog-like dark-ambient pads, 6 patches,
     bank 14: tastierebarocche.syx, acoustic and electric keyboards emulations, 26 patches
     bank 15: vociatroci.syx, human strange voice emulations, 20 patches

I think my patches are pretty unusual soundscapes also for the DX7II synth. The soundcapes genre is Techno music, dark-Ambient music, Electronic-Experimental music, Psychedelic music, beside I studied to emulate also acoustical and vintage electronic synths; I love especially brass sounds (there are beloved  trombones in brassonerie.syx, electric organs in orgiaorgani.syx, cembalos on tastierebarocche.syx, etc. etc.). It's strange that a digital synth like FM DX7II have a real/likely acoustical emulation of strings, brass and percussions. All in all re-listening my patches nowadays (many years ago after times when I programmed these), I feel that crippled psychedelic, analogic-sounding, fuzzed-freak sounds, are really suitable for TECHNO music contexts, and  real-time controllers programming I realized in many patches, are the cherry on the cake for techno-dance live performances!

Some programming technical details


About micro-tunings: In the most of cases I programmed almost 64 voices and 32 performances, but I do not programmed special micro-tuning intonation; this is because: On one hand, years ago I didn’t have the sensitivity and the musical technical knowledge for appreciate microtonal intonations outside the "equal temperament". Indeed at the moment I am very interested in Just Tunings, but at times when I programmed DX7II I, I didn’t have the knowledge for program my tuning ideas... maybe because I have not an editor for do that. Btw, JI Calculator, is free Mac microtuning utility by Robert Rich. On the other hand, many patches I programmed simply do not have any particular intonations: many times are drones, atonal "noise" sounds, not intended for a "classical" keyboard player, but mainly for techno-ambient-electronic music environments.

About DX7II MIDI controllers: in many (but not in all) cases I programmed performance sounds as stereo, programming in detail CS1/CS2 slider sensitive, modulation/picth weels sensitive, velocity/after-touch sensitive, with some keyboard mapping. Please note that I didn’t program any Foot Controller (because at programming times I didn’t posses one). Anyway it’s very simple to modify patches to add this feature (in facts it’s important to control volume swell especially, because in some slow-motion complex patches, because the lack of DX7II polyphonic power, it’s a good idea to smooth attack with volume pedal to avoid some attack transitory noises-clicks). Please note that my patches are some time extreme-programming put DX7II at his limits regarding polifony, etc. (I mainly used long decay, bundle patches, etc.).


About stereo (pan) feature: please remember to switch on (see photo below) is you like stereo output! In my model pan-on is not a default and you have to switch on manually! In facts pan (= stereo) mode on DX7II do not run perfectly and you could prefer to switch off, resulting in a mono output (mixing together left and right channels).

About excessive velocity sensitivity of the patches: I have check my sounds on my particular DX7II that have a know "firmware bug", so my DX7II can not achieve all the velocity dynamic (0-127), but instead I have a limited (0-1xx) dynamic, this is because probably many sounds seem to be too loud on velocity touch; simply play soft :)

About DX7 outputs audio postprocessing: I think that DX7 audio signal is too poor, cold, harsh, to put them directly in the mixer, so I get the best results putting the synth outputs into a multieffects for some riverberation (obligatory in my opinion) and delays effects (for that I programmed many delays patches on a ART Multiverb Alpha).


How to buy DX7II Patches  

You can buy now via Paypal account! 393 original patches collection cost is 39 EUR


Payment steps:

  1. Please send an e-mail at solyarisMusic@gmail.com before any payment, in this way you will be sure that I can feedback and sell in a reasonable agreed time framework. If you don’t receive my feedback via e-mail this means that I am temporarily unavailable, but usually I could reply in few days.
  1. Make the payment to the Paypal Account I’ll feedback to you.
  1. After payment I’ll mail you all info to download patches (encrypted zip file + password).


Please note that now I can accept only Paypal payment also with a credit card transaction, please assure you to get your Paypal Account before make any payment (see www.paypal.com  for details). Please do not ask me Paypal process understanding / general concepts user help.


How to use DX7II Patches


About upload patches into DX7II: After download the .zip file at URL I’ll specify when received payment, you need to extract/decrypt patches files from the .zip container, and finally you will able to upload sounds into the DX7II. All files (/sysex/*.syx) are in SYSEX format, so you can use any sysex utility sw, a program that can transmit and receive system exclusive (sysex) messages via MIDI to your DX7II, loading patches files .syx from disk file stored on personal computer. About sysex upload/download utilities on personal computers, I used MIDI-OX on PC and Sysex Utility on Macintosh.


Important note: I currently do not more program DX7II and I have difficult to give you technical detailed assistance on using DX7II, managing sounds, etc. Please buy sound patches here only if you already have good skills on personal computer usage and DX7II (almost basic) programming. Last but not least, on.txt files and README files you will found obsolete reference to my e-mail and web site (no more valid); please refer to this website and e-mail address here specified to contact me.
