AMPT User's Guide

An AMPT Device is a device that processes MIDI messages. A device can be either hardware or software, and is represented on the Canvas by a box.

Devices that are provided by the AMPT Team (such as the Arpegiator), or can be configured (such as the Java Synthesizer) are displayed with the options for that device.

Devices can provide many different functionalities by creating, altering, or processing MIDI messages.

Devices that can be added to the canvas are located in the Canvas Toolbar.

In order to add a device to the canvas, first select which device you want to add by clicking on that device in the Canvas Toolbar. Then, click on the location on the canvas that you wish to place the device.

Once a Device has been placed on the canvas, you can still re-position it. To move the Device, click on it and drag it to the desired new location for the Device. If you drag the device outside the canvas, the canvas will scroll in that direction until it reaches the border of the canvas.

If you are having trouble moving the Device, make sure you are not clicking and dragging on a portion of the Device designed for user input, such as a Combo Box, or a Slider! It is typically safe to click on the portion of the Device where the name is displayed

In order to remove a Device that has been placed on the canvas, right-click on the device, and then select "Remove MIDI Device".

If you are having trouble with the right-click menu showing up, make sure you are not clicking on a portion of the Device designed for user input, such as a Combo Box, or a Slider! It is typically safe to click on the portion of the Device ox where the name of the box is displayed.

In order to connect two Devices so the MIDI messages can travel from one to the other, first right-click on the Device that is transmiting the MIDI messages. Then, choose "Add Filter Connection". Finally, left-click on the Device that is receiving the MIDI messages. If the connection has been made, there will be a line displayed on the canvas, with an arrow in the middle of it showing the direction the MIDI messages will be traveling.

NOT ALL DEVICES CAN BOTH TRANSMIT AND RECEIVE MIDI MESSAGES!!!

You should note that all Devices either have an arrow pointing into the Device on the left, an arrow pointing out from the Device on the right, or even both! Arrows pointing into the device from the left mean that Device can receive MIDI messages. Arrows pointing out from the Device mean that Device can transmit MIDI messages. If a Device has both arrows, then it can both receive and transmit MIDI messages.

In order to disconnect two Devices so that the MIDI messages no longer travel from one to the other, right-click on either device. In the pop-up menu, hover your mouse over the "Remove Filter Connection" option, and a second menu will appear with all the Devices that the selected Device is connected to. Devices that the selected Device receives messages from will be prefaced with "From:", while Devices that the selected Device transmits messages to will be prefaced with "To:". On the extended menu, choose the Device that you wish to disconnect the selected Device from, and the Devices will no longer transmit messages to each other. You should see the line connecting the two devices disappear.
