Lambdoma Com Ports

Lambdoma Com Ports

For those who have Barbara Hero's Lambdoma keyboard connecting via a Com port...

You use this to configure FTS to retune your Com Ports keyboard. to the Lambdoma.

If you have her MIDI lambdoma keyboard, UNSELECT In | Show Options for Com Ports keyboard which will hide this button and show another button you can use to configure FTS to work with your keyboard.

How to get here

In the Lambdoma tasks: SELECT In | Show Options for Com Ports keyboard.

Then, click the Com Ports button in the main window for the Lambdoma tasks. Or use the keyboard shortcut Ctrl + 129

How to use this window

All you have to do in this window is to select which Com port your keyboard is connected to (or which ports, if you are using a multi-quadrant keyboard).

The part to play shows which part you are using in the Parts window - this is the one you need to select an instrument into, to change the sounds for your keyboard. Normally you can leave this at its preset value of 1.

The other fields are all for diagnostics. If your keyboard is connected properly then you will see details of each note as it is played. This may slow down playing - if so close this window, or unselect Show events here.

If your computer has USB and no com ports, you need to use a USB com port. Search for an RS232 adaptor. I've used the US232b from EasySync successfully

Open Com ports for Lambdoma keyboard input

Opens your Com port(s) ready to receive notes from Com Ports Lambdoma keyboard...

Configured using the Lambdoma Com Ports (Ctrl + 129).

Add to In Menu...

Add "Open Com ports for Lambdoma keyboard input" to In Menu

Test

Preliminary test that your com port works okay if you don't have a keyboard yet...

To do this test, you need to have two Com ports installed, and a com port cable. Also the com ports must be consecutively numbered (they usually are numbers 1 and 2 if you have one of the older desktop PCs with com ports).

Connect one port around to the other one. Select the highest numbered of the two ports (port 2 on a p.c. normally). Then use this button and see if you get any notes played.

The way it works is that FTS will generate some data and send it out on the port before the currently open port. If all is well you should hear some notes played when the data comes back through the other port.

Special options:

Ctrl + Yes to test 2 notes, Shift for 4, Ctrl + shift for 8, Ctrl + Alt for 16, Shift + Alt for 32, and Ctrl + Shift + Alt + Yes to test all 64 possible notes. Just plain Yes to test a single note.

If unsure which com port to use, try them all until you find the one that receives notes from your keyboard. Use the Find Open Ports button to find out which ones to try.

Use this option if you find open Com Ports with numbers higher than 4, or if the documentation for your hardware says that it connects using a port number higher than 4.

Multi quadrant

Set up for two or four quadrant Com Ports keyboard

Port

Enter the com port number to use

Port - SPIN

Increase or decrease the custom com port number

Select the ports to play and the offsets for each quadrant for your keyboard

Ports

List all the com ports that receive notes from for your keyboard

Offsets

Offsets for first row for each quadrant in the larger Lambdoma...

Enter the row offsets for each quadrant in turn.

When this is 0, the first row of the quadrant plays the top row of the 16 by 16 Lambdoma. When set to 8, the first row of the quadrant plays the middle row of the 16 by 16.

For diamond layout, the "rows" are the rows of cells running diagonally down to the right.

by

Offsets for first column for each quadrant in the larger Lambdoma...

Enter the column offsets for each quadrant in turn.

When this is 0, the first column of the quadrant plays the first column of the 16 by 16 Lambdoma. When set to 8, the first column of the quadrant plays the middle column of the 16 by 16.

For diamond layout, the "columns" are the columns of cells running diagonally up to the right.

Find Open Ports

Find which com ports are available on your machine...

It is a quick way to find the port to use if not sure of the number.

This search will normally take twenty seconds or so (allowing two seconds to wait for a reply for each port up to port 10).

It should find your com port if the number is less than 10 - usually it will be. If not, consult the documentation for your hardware.

If no com ports are available, you need to install one. If you have USB you should be able to connect a com port to your computer using a USB com ports cable (protocol RS232).

Part to play from Keyboard

Set which part to play for PC Keyboard player and Lambdoma keyboards...

You use the Parts (Ctrl + 9) window to set up an instrument for a part along with the volume, octave shift and other parameters.

If unsure you can leave this as 1, it doesn't matter which part you use - but whichever number you use here is the one you need to change in the Parts window if you want to play the notes on a different instrument etc.

This part is used when you play the parts using the PC Keyboard and mouse, or using one of the Lambdoma keyboards.

Composers may want to select In As | select PARTS BY for current Lambdoma Device - same as other Midi In ... and set it to Select Parts by Input Chann - as this lets you retune scores with several instruments playing simultaneously. See Retune compositions with FTS Check List

Part to play from Keyboard - SPIN

Adjust the part to play for PC Keyboard or Lambdoma keyboards up or down

Show events here

This will show all the com port events received by FTS...

This may well slow things down whenever this keyboard is visible - but gives immediate feedback about whether FTS is receiving notes or not.

It also shows step by step what happens when FTS attempts to connect to the com port, which is useful for diagnosis if anything goes wrong there.

With times

Show times when the com port events were received

This can be useful for diagnostics.

Reset all com port parameters on open

You may want to unselect this for a USB com port

The reset is done temporarily for the FTS connection, so won't affect anything else on your computer. Normally best to have this selected, to make sure that the com port is always set up correctly to work with FTS.

Try unselecting this if you are using a USB com port as it may have special requirements. Then FTS will use the original parameters for the USB com port for all except the ones that need to be changed to use the keyboard.

If unsure, most users should leave this option selected. If you use a USB com port and it isn't working, you may want to try it again with this check box unselected.

Detect <CR>

Detects the carriage return sent by the keyboard after every note...

This means that the com port will treat its buffer as filled when it detects the carriage return sent by the keyboard after every note.

This may be worth trying if you are using a USB com port and find that notes don't get received (or sometimes get lost).

Another thing to try is to configure the latency of the com port, it may help to reduce the latency to its minimum setting e.g. 1 ms - and the buffer should be as small as possible - try your Com Port's advanced settings if available from Control Panel | System | Device Manager | Com Ports.

Note Off velocity

Normally 127. You can make it less to switch off notes more gently...

Most out devices will ignore this number. But if you are using a device which lets you configure how notes are switched off, you can set this to a number less than 127 to switch the notes off more gently when you release a key on the Lambdoma keyboard.

This shows that the keyboard is active. You will also see diagnostics here when FTS attempts to open the com port.

This may slow down your playing - but only when this window is visible. You can switch this off by unselecting Show events here.

Whether times are shown here depends on whether you have With times selected.

Help = F1

If there is no on-line page specific to a task, takes you to the main tune smithy page on the web site.

Since the help for Tune Smithy is currently a bit out of date and needs to be redone completely for the new 3.0 release, then you may find the on-line page for some of the newer tasks particularly useful.
