We sent out the first betas for SSEYO Koan branded apps in 1992 and initially called the music it made "Koan Music". The genre later became better known as "Generative Music" and 25+ years later SSEYO Koan would go on to become IntermorphicWOTJA. See credits.
In 1994 we published Koan Plus and, at about the time in 1995 as we were readying Koan Pro V1.0 authoring system for release, we were lucky enough to bring it to the attention of Brian Eno. In autumn 1995 Eno started working with Koan Pro (superceded by Noatikl in 2007 then Wotja in 2017) culminating in the 1996 release of Generative Music 1 with SSEYO Koan Software.
A number of internet and mobile developments ensued for Koan between 1997 and 2002, a crucial one being that we added to the SKME an integral sound engine called the SSEYO Koan Sound Engine (SKSE).
In 2002 SSEYO was then acquired by Tao Group, at which point SSEYO Koan sadly passed away (it's gone, meaning it's not been developed or supported since 2002). As SSEYO Koan's developers, though, we (Intermorphic) got back all the SSEYO IP in 2008 and have now retired it. However...
Having found us, despair not!
SSEYO Koan has evolved and now lives on in Wotja, see below...
SKME + SKSE > IME + ISE
1992-2007: The SSEYO Koan Engines
Generative music apps are all about the music engine and sound engine that underpins them.
The SSEYO Koan Music Engine (SKME) and SSEYO Koan Sound Engine (SKSE) were built by us and have now gone, as are the various SSEYO Koan apps that used them. The good news is that at Intermorphic we develop (and are continuing to develop) engines that are more powerful than the SKME and SKSE.
2008-2016: Noatikl Music Engine (NME) and Partikl Sound Engine (PSE)
At Intermorphic, we started with the Noatikl Music Engine (NME) and Partikl Sound Engine (PSE) that were at the heart of Noatikl 3, Mixtikl 7, Wotja 3 and Tiklbox 1. The NME was a clean room build engine that leveraged the 15+ man years of experience we gained from developing the SKME, and the PSE leveraged our experience developing the SKSE and also the mobile audio work we did at Tao. Note that the Noatikl Music Engine was NOT the SSEYO Koan Music Engine, but was very like it and could open Koan files created with any version of Koan Pro (i.e. right back to 1992) or Koan X - which means you haven't lost your old work. See the FAQ below.
2017: Intermorphic Music Engine (IME) and Intermorphic Sound Engine (ISE)
Yes you can! Get Wotja V20.2.1+ and you can open them directly.
Note that if you used the SKSE (Koan Synth) for sounds then those settings will not be imported correctly. That is because Wotja uses a different synth engine in the ISE. You may get something imported, but it is highly likely not to sound as you remembered.
While we can open old skd files (see above) and use most of the parameters as originally intended, we're unable to import old SKSE (Koan Synth network definitions. The reason for this is that the old format is very substantially different to the new format used by Intermorphic Sound Engine (ISE). Wotja includes a large number of Sound and FX Presets which you can use as starting points.
IMPORTANT: The files must have been saved by Koan Pro V1.3 (1996) or later and so be of V1.3 format.
SSEYO Koan .skd/.skt file
Just open it with Noatikl, and start using it!
Synth definitions aren't copied across (see this FAQ entry), old AWE/XG parameters aren't copied either. If you want to know about these, e.g. to re-create with our soft synth, look under your <Noatikl data folder>/"Koan SKD Import Logs" folder for a text file that gives a full text dump of what was in the .skd file you imported.
Piece root parameter lists are turned into parameters like "A B C#" containing all permutations; one of those values is selected randomly at piece start, a per usual.
All other Parameter lists are turned into start Scripts automatically; Voice parameters are put in the Voice start script, all other objects are put in the Piece start script;
You can fiddle with those scripts if you want to change the probabilities at all.
SSEYO Koan .skm file
Open with Noatikl...
... if you open one of these, you get a dialog asking you if you want to export:
if you want to export the files to the <Noatikl data folder/"Koan SKM File Imports" folder;
if you agree, the .skd/.mid/.mp3/.dls files are all extracted and saved to that folder.
You can then do what you want with those file (e.g. open the .skd file with Noatikl etc.)
Tao Group SKM file with the Tao-era soft synth
Should just work!
Tao Group SKM file (e.g. with embedded .skd file and embedded DLS/Ogg)
Should just work!
You might have to change some of the patches to match the wavetable definitions; e.g. in change patch from 1.1 to (say) 1 or 1.0 (assuming the Ogg wavetable bank is zero); this is due to a bug in the old Koan software.
Tao Group SKM file (e.g. with embedded .mid file)
You get a dialog telling you to try again, but with a specifically named .skd file in a specific folder.
Put the original .skd file in that folder, and rename as requested
Re-open the skm file
Should just work!
As before, might have to change some of the patches to match the wavetable definitions; e.g. in change patch from 1.1 to 1 (assuming the Ogg wavetable bank is zero); this is due to a bug in the old Koan software.
