Secondary Menu

This update comes with the start of menu expansion on GRID BLASTER. From the last iteration, the system works for step sequences but the playback options are very limited to just a single Sin osc and a few wav clips. There was no volume control or a mute button which can be very useful to change up layer use and diversify the final recording. I decided to make a separate menu that can control volume levels per layer and also added a mute button. Currently this menu is very bare and the volume bar doesn't work but its a first step to being able to have different menus use the main grid instead the step sequencer. I am planing to make the volume bar into a double bar for panning control and to change this menu from being on the "Note" button to being the second click when the layer button is the current board. I wanna change this so that its better to tell what layer your looking at and so that I can make the note menu into a synth dial menu which I will need todo more research into delays and other cool effects.
