Max 7 Harmonizer Patch

This patch came about through adopting a more bespoke approach to audio processing in an effort to further develop an individual instrumental and compositional voice. Coded in Max 7, the patch uses the gizmo~ object inside an FFT sub-patch to analyse peaks within given FFT bins before moving them along the frequency axis, shifting the sound up or down in pitch. Max 7 makes pitch shifting even easier with the inclusion of separate specific pitch shift objects without the need for a pfft~ shell however I still prefer to use pfft~ sub patches as they allow individual control over the FFT bin resolution.

The patch also includes volume envelope control based amplitude threshold detection of the incoming audio signal and four individual delay lines (not shown in the patcher pic) routed to the two stereo output channels in pairs. In addition this post also marks a move towards recording video to document specific elements of the…
