Methodology and Instruction of MaxMSP For my assignment I was tasked with creating my own max patch that can load prerecorded sound files and feed live audio, both being exposed to at least 2 audio processes which have at least one variable parameter each. When creating the max patch I started with the loading of sound files and the feeding of live audio. I used a pre-constructed open and play audio files patch located on blackboard(1) as well as placed an ezdac~ audio input button. The first effect the audio goes through is a pitch shift patch, this is a pre-constructed patch found on blackboard(2) with it’s variable parameters being a slider to change the pitch as well as a random button to continuously change the pitch of the audio and a centre button to revert the audio back to normal. Once the audio goes through the pitch shift it then gets exposed to a delay called real time stretching where the audio is elongated, this was created by following a youtube tutorial I accessed on 27th May 2017 at 12:38pm (3). It’s variable parameters are two messages, one editable to change how long the audio is stretched and one message that is set to 0 for normality. Following the two audio processes I inputted a gain~ exponential scaling volume slider for better control of how loud the audio will be, linked to an ezdac~ audio output and on/off button. To use the max patch you have a choice of either patching through a microphone or live feed to the patch using the audio input, or load a pre-recorded sound via using the open message or dragging and dropping the sound into the box above the patch. After that you can simply press the audio output button which will then play the original audio without any effects, as this is going on this is when you can start playing with the effects. With the pitch shift you can use the slider as the audio is playing or press the random button to allow the effect to increase and decrease at it’s own pace. With the delay effect, before playing the sound you can edit the message on the right to stretch it as far as you want, for example I could edit the message from 0, 13000 20000 to 0, 59855 100000 and the playback will be stretched further than with the previous message. If you feel it is too loud just use the volume slider and there you go. The final audio I recorded is an example of what the two processes produce solo and together. You hear original audio at the start for 12 seconds before the example of the pitch shift running from 12 seconds to 26 seconds in. At 30 seconds the example of the delay is shown for 10 seconds and at 48 seconds into the recording until the end is both effects going on at once producing the file sound.
