Yamaha CS-15 drone sounds

December 23, 2007

Here are some drony kind of sounds I recorded before selling my Yamaha CS-15 with the intention of showing some of the sounds the synth is capable of.

CS-15 flowchart

The CS-15 is a pretty flexible analog synthesizer, thanks to it having two of everything – except for the one LFO (which goes up to 1000 hz – fast!). The envelopes are fast and snappy, though not as powerful as the ones on the lesser model, the one-oscillator CS-10. But you can not demand much more from such a cheap and still well built synthesizer. Of course you are left wishing for some features – for example it is lacking in inter-oscillator modulation, no cross-mod, sync or the likes despite two oscillators.

The two state-variable filters (LPF, BPF, HPF) are not exactly “creamy” and pleasant in ways like the moog filter or the Roland SH-series – but they are very competent and useful when it comes to soundsculpting. They have a distinct character, and are not really bland sounding. Highly resonant sounds are not one of it’s strong points, but it does well across board otherwise.

Modifications can remedy some issues, for example enabling the option of routing the filter both in parallell and serial. Both filters in bandpass mode, serially connected, with separate CV-sources controlling the cutoff makes for some very nice sounding vowel type sounds.

OS1.50d for Elektron Machinedrum released

December 23, 2007

The good people at Elektron ESI AB have released a major update of the OS for the Machinedrums, just in time for christmas! This update is both for the MD classic and newly released MD mkII. Here are the most noteworthy ones:

  • Four new CTR (control) Machines are available – each controlling one of the master effects. Yay!
      • Also some (much needed) bugfixes on the behaviour of the RAM machines is introduced
      • UNDO functions has been implemented for a lot of operations.

      When I got my MD a few years ago, after getting to know the basics, one of the first thing I thought was “hm, shouldn’t it be possible to do have parameter locks affect the internal effects?” Now you can, for example, control the delay time or feedback values for the Rhyhtm Echo by using parameterlocks. Doing the same with the gate time for the gate box, EQ parameters and compressor settings surely opens up a lot of possibilites.

      Some of the CTRL-machines added in earlier revisions of the OS didn’t have the possiblity of using the LFO’s to control parameters, something which is understandable for practical reasons. The new effect control machines however can have LFO’s routed to them – also a neat function.
