[linux-audio-user] Re: [Alsamodular-user] [ANN] ams-1.8.6 - Barber Poles

Hello, recently I discovered cool Barber Pole modules on Don Buchla's page (www.buchla.com). I remembered that the manual of my Doepfer system mentioned something about these effects, so I looked it up (you can also find it online at www.doepfer.de/a191.htm) and started to implement a special LFO for generation of Shepard tones and other spiral sound effects. Here is the result: ams-1.8.6 with several barberpole patches in the demos folder. Pitch- and ModWheel are bound in most examples. Try to set Gain Saw to 1.334 in the Barber Pole module of example_barberpole.ams. It might also be interesting to further decrease the LFO frequency. Note: You may have to adjust the mixer/PCM Out volumes when playing the examples polyphonically. Don't forget that AlsaModularSynth requires the MCP/VCO/REV plugins by Fons Adriaensen. Efficiency and power of Fons' phaser is seen in example_barberpole_phaser* where 8 of them are used in a single patch. Have a lot of fun ! Matthias
