The phase offset is then added to the raw phasor~ output (with a +~ object), and then wrapped to the range 0.0 to 1.0 with a wrap~. This is all contained in a randoffset subpatch. This is then scaled back by dividing by the number of 8th note to give a 8th note quantized phase position in the range 0.0 to 1.0. The offset is calculated by taking the number of bars in the loop, multiplying by 8 to get the number of 8th notes, and generating a random number in this range. A random 2 and s el 0 object pair ensures that only half of the metro bangs are processed. There is a 50% chance that randomization occurs every 8th note. The position of the hslider thumb is updated to reflect this value. The slider range is set in response to a sample_count message (ie, when a new audio file is opened.) The current play index of the scaled phasor~ is sampled using a snapshot~ object, which periodically generates a value in response to a metro object running at 10 frames per second. This frequency, the reciprocal of the loop length in seconds, is calculated in the len2freq subpatch.Ī hslider (horizontal slider) object shows the current playing position beneath the waveform display. To play back the sample at its original tempo, we set the phasor~ to run at a frequency so that a single phasor~ period takes the same time as a single cycle of the loop. The phasor~ generates a floating point signal that ranges from 0.0 to 1.0, which is then multiplied by the number of samples in our audio file to give a range between 0.0 and the number of samples. The sample loop is played back using a phasor~ which provides an index to a tabread4~ object. #RENOISE SAMPLER SET POLYPHONY LIMIT PATCH#The size of the audio file, in samples, is output by the soundfiler object, a value which is accessible elsewhere in the patch with the r $0-sample_count recieve objects. We specify the -resize flag in our message to soundfiler to inform the array to set the correct size required for the selected audio file. A soundfiler object then reads the audio sample into the specified array in response to the read message. ![]() The Open File browser is displayed by sending a bang to an openpanel object, which in turn sends a message containing the selected filename. ![]() The pitch of one oscillator is slowly detuned relative to the other to introduce beating: Here are two raw sawtooth oscillator, with no filtering, tuned octaves apart.
