To output matrix values to a number box, use metro 1000 to bang a counter object, and use that output as the matrix coordinate for the getcell message. Please note that the third outlet of counter does not send out a bang unless you tell it to (with a carrybang message). It sends out a 1 when the counter reaches its maximum, and a 0 on the next output. This causes a double trigger.
Once you get to a large number of booleans, you might want to pack all those 0/1 states together as a single integer and use that integer to look up a behavior. Here’s an example using four booleans; extend and alter to suit your needs.
This abstraction expects to get a number in any of its inlets, and will pass the number out the corresponding outlet, but before doing so it will send a 0 out the previous outlet.
Taking 0 to the power of any negative exponent equals infinity. In Max, this yields the unique float value inf. In cases where you want to avoid getting inf, and would prefer to get 0, you can simply make a special case for a 0 input, and pass it on directly, avoiding the pow object. On the left is an example of how to use routepass to force Max to output 0 when it would otherwise calculate infinity, such as when using a pow -1 object.
This patch monitors data and outputs a bang when no change is detected.
To achieve delays that are quantized to a named transport, use a combination of pipe (delay numbers by the desired amount), translate (to set the pipe to the desired delay time), zl group (hold onto numbers as they come out of the pipe) and metro (following a particular named transport and quantized to the time unit you want).
This example demonstrates how to make a slider object spring back to a specified value.
This example demonstrates a very simple setup for playing a MIDI file.
This patch contains examples of useful messages for playing MIDI files with the seq object.
This example shows how to retrieve a list of MIDI input devices and display them in a umenu object.
