Casio CZ-101

It's small, it's cheap, and it's good! This is the pea-size version of the CZ-1000 with a mini-keyboard. The CZ-101 is a digital synth and although the programming is somewhat limited there are plenty of analog-like traits and sounds to interest most anybody. It has a good 8-stage envelope design and uses Phase Distortion (PD) synthesis which gives it some pretty great sounds. The sounds are very similar to the Yamaha DX synthesizers, and they're much more affordable. PD is Casio's own take on digital synthesis from the mid-eighties and is found in all of their CZ series. You basically modify digital waveforms (sine waves) to create various sounds. It can create wild new sounds, notably percussive sounds. But it's not too easy to program if you don't know much about waveform theory and design.

Make no mistake, the CZ-101 is no toy although it can be considered very entry level. Three sets of 8-stage envelope sections are used to modulate your sounds extensively. The first is used to modify the DCO pitches over time. Another 8-stage envelope section in the DCW is used to modify the Phase Angle over time (like filtering). Finally the DCA amplifier also has an 8-stage envelope to modify the volume of sounds over time. For further tweaking the CZ-101 employs some surprisingly analog effects. Four types of Vibrato make up a simple LFO-type section with triangle, square, ramp up or down waveforms as well as rate, depth and delay settings. Portamento adds that classic glide effect from one note to the next. Double up on the oscillators with 4-note polyphony. Built-in noise and ring modulation. It's also MIDI equipped with 4 monophonic multitimbral parts. However, with only 32 patches (16 preset, 16 user) storage is a bit slim.

The CZ-1000 is a full-size keyboard version of the CZ-101 for a slightly more practical edge. Later CZ-series models like the CZ-3000 and CZ-5000 used this new Phase Distortion synthesis in more professional instruments. But none are as small and portable as the CZ-101 is! It can even be strapped on like a guitar and run on battery power. The CZ-101 has been used by Cirrus, Moby, Jimi Tenor, Vince Clarke, Jimmy Edgar, and They Might Be Giants.

I really like the grainy digital character of its sound, reminds me of 8 bit PPG or Emulator, especially when the ringmodulator is activ. PD CAN sound similar to FM, but there are clear differnces between both. PD is not as glassy and harsh as Yamaha DX, but therefore capable of a warmer rounder, but still edgy tone and it is has definitely more punch at the bottom end. Poor cpu makes some fun glitchy artefacts when all voices are played. A truely unique synth!

These are relatively easy to edit although I am not sure I would recommend one for somebody completely new to synths. This is in part due to the fact that the programming method is kind of unusual. I would say go with a microbrute if you're about to drop $300 on synth for the simple fact that all of the parameters are labeled and its just a better machine in general. I got this as my first synthesizer and I can say it didn't teach me much, though it is a wonderful instrument.

These are so much fun. One thing that is slightly bothersome is that if you hold a key while editing a parameter, the audio will kind of stutter in sync with the value as it changes. This may just be my synth, though. Also, all of your saved patches (not including presets) will erase if it is unplugged for ~ ten minutes. I am currently just keeping 6 d cells in it to save my patches when transporting it, and then I just plug it in wherever I end up taking it. Last thing, I had some problems with the factory lcd when I got mine, so I swapped it with a backlit one and it is perfect now.

It does not sound "similar" to a FM synth at all. In comparison to an FM-synth this synth is a breeze to edit in my experience, preferably using a program on your computer (like sounddiver). Patch space can be upgraded either with the original cartridge (16 patches, but there is a mod to give you 32 patches on it), or with the third party "EZ-CZ cartridge" you get 4x16=64 patches of space! And yea, go download a nice bank I made for it: http://andreasostling.se/synth.html
