Is There an If? for flute and electronics

Shu-Yu Lin May 2020

Explanatory notes

Flute

1/8 tone flatter (-1/8)

1/8 tone sharper (+1/8)

Slow vibrato, approximately 1 pulse each second

Electronics

Press button 1 on controller to trigger electronics; ‘2’ refers to press button 2 etc.

Press it again to stop processing.

Press button f-1-8 to amplify flute through speakers 1, 2, 3, 4, 5, 6, 7 and 8.

Button f1 refers to amplify flute through speaker 1, f2 through speaker 2 etc.

Button f-o refers to amplify through odd number speakers.

Button f-e refers to amplify through even number speakers. f1-p amplification consists of panning function which can be controlled using knob 1 (further explanation see below regarding knobs).

Press it again to stop amplification.

Press button rec1-17s to start record flute for 17 seconds; rec1-2s refers to record flute for 2 seconds, rec1-5s refers to record flute for 5 seconds etc.

Names of the recording buffers are in sequence. For example, rec1-2s and rec2-2s both record for 2 seconds but into separate buffers.

Button will be auto off at the end of the recording. There is no need to press it again to stop.

Press button p-rec1-17s to playback recording rec1-17s.

Button will be auto off at the end of the playback. There is no need to press it again to stop.

Turn knob 1 (k1) on controller accordingly to modify computer-generated sound; k2 refers to knob 2 etc.

See below for further detail on the knob control parameter.

Adjust slider on controller accordingly to modify output amplification.

See below for further detail on the slider control parameter.

Electronics control parameter Knob: Knobs 1 and 8s should be turned to 0 as the default before the performance.

Knobs 3, 4, 5, 6, 7 should be turned to 1/2 (63.5 of 127) as the default. Electronics performer is free to adjust the reverberation according to the characteristics of the performance venue.

Knob 1 (k1) controls the panning of the input signal and knob 8 (k8) controls the panning of the granular synth output. On the score, speaker number is specified with midi output number, which is shown in the console, for panning precision. If the panning midi number specified 71, pan to values between 69-73 is acceptable.

figure showing processing button 7 with granular panning control k8 with specified starting speaker 1 in which the midi number is 0, and pan to speaker 1 to complete a panning cycle with midi number 127

Knob 3 (k3) controls the dry and wet gain of the reverberation, in which 0 represents the driest, 127 the wettest.

Knob 4 (k4) controls the room size of the reverberation, in which 0 represents the smallest and 127 the largest.

Knob 5 (k5) controls the duration of grain in granular synth. Midi number 0 represents the shortest duration and 127 the longest. Values are written between 0, the minimum and 1, the maximum. For example, the value 1/4 indicates to adjust k5 to 1/4 of 1 etc.

Knob 6 (k6) controls the frequency of grain in granular synth. Midi number 0 represents the lowest and 127 the highest. Values are written between 0, the minimum and 1, the maximum. For example, the value 2/4 indicates to adjust k6 to 2/4 of 1 etc.

Knob 7 (k7) controls the cloud density in granular synth. Midi number 0 represents the lightest and 127 the densest. Values are written between 0, the minimum and 1, the maximum. For example, the value 3/4 indicates to adjust k7 to 3/4 of 1 etc.

Slider: The sliders controls the amplitude of the specific processing output. They should be turn to the maximum as default before the performance.

Slider values are written between 0, the minimum and 1, the maximum. For example, the value 1/4 indicates to adjust slider to 1/4 of 1.
