I guessed that the K4 somehow creates 16 bit samples by combining the contents of the chips together. To my surprise, chips U39 and U40 sounded just fine now! A little bit of 8 bit noise, but nothing unexpected. I changed the import format and loaded them again. This can be seen by adjacent bytes constantly rising or falling, as below: I looked at the data in a hex editor and was surprised to find content that much more looked like 8 bit samples rather than 16 bit samples. What I also noticed is, that the former two chips sounded a bit distorted, had a lot of noise and the pitch seemed to be pretty high. While I had no issues with chips U39 and U40, chip U38 (the rightmost one in the picture above) sounded like garbage. I imported the raw data as 16 bit and listened. As the K4 claims to be a 16 bit sampler, it was expected that it needs more storage for the samples.Īfter having dumped all of them, which was very easy due to them being socketed this time, I loaded them into my wave editor to take a first look. In contrast to the K1, the K4 has three Wave ROMs in total.įrom left to right: Kawai K4 Wave ROM chips U40, U39, U38 I dumped the firmware just to verify that the content on the chip matches the firmware image that I already had on disk, which it does. The first thing I did is to dump the contents of the Firmware EPROM and the Wave ROMs. It’s available as a free download.I started to analyze the K4r.
It runs in Java and works on Linux, Mac & Windows. The update also features several new patch exploration tools, including real-time morphing between four patches, and merging of random patch pairs from your synthesizer.Īt present Edisyn supports: the Alesis D4 and DM5 Casio CZ series DSI Prophet ’08, Mopho series, and Tetra E-Mu Proteus 1/2/3, Morpheus, and UltraProteus Kawai K1, K4, and K5 Korg MicroKorg, MicroSampler, SG Rack, and Wavestation SR M-Audio Venom Novation Drumstation and D Station Oberheim Matrix 6, 6R, and 1000 Preen FM2 Red Sound DarkStar Roland D-110, JV-80, and JV-880 Waldorf Blofeld, Microwave XT and XTk, and Kyra most Yamaha 4-Operator FM Synths (such as the TX81Z and DX11) Yamaha FB-01 Yamaha DX7, TX7, TX216/816, Dexed, Korg Volca FM, and other DX-7 compatible synths Yamaha FS1R Yamaha TG33, SY22, and SY35 Tuning standards and MTS and generic CC, NRPN, and RPN control.Įdisyn has infinite levels of undo, a broad spectrum of patch exploration and creation tools (mutation, merging, nudging, morphing, blending, and evolutionary methods), and a wide array of other useful features. Version 26 has new editors for the M-Audio Venom, Waldorf Kyra, and Casio CZ-230S. Edisyn, a free open source patch editor, has been updated with support for more synths and more.
