Tune Smithy – Lambdoma Task

Tune Smithy - Lambdoma Task

The Lambdoma task in Tune Smithy let’s you play on an arrangement of musical ratios attributed to Pythagoras in which notes all in the same row or column play pure musical harmonies. The particular design and colour of this keyboard is due to Barbara Hero. You can play it using the mouse or the p.c. keyboard.

The p.c. keyboard has some limitations as a musical instrument – so only four rows at a time are accessible. It is also normal to find that many chords of three or more notes can’t be played from your p.c. keyboard.

To use this task without those limitations, you need Barbara Hero’s keyboard – see for details. You get an unlock key when you purchase the keyboard.

This page is for any users of FTS who want the Lambdoma view for use with mouse or p.c. keyboard on its own. Please use this page to order it if you do so, so that Barbara Hero can be credited with a commission for your order, as an acknowledgement of her role in the development of this part of Tune Smithy.

Most users of the Lambdoma task purchase the Midi Relaying unlock key. But if you want to get the polyrhythm metronome or the fractal tunes as well, order the complete unlock key.

Robert Inventor’s mini utilities

Robert Inventor's mini utilities

ACTIVITY TIMER is a computer activity, project or task timer. It keeps track of the time you spend at the computer on your various projects. You can also set it to automatically change project when you use particular windows. You can show the time worked for any period, by week or by day, with an option to show costs for the times based on a price per hour worked

You can also play sounds or show a variety of screen alarms as a reminder that it is time to stop work.

The other main thing it can do is to play or show reminders to look away from the screen for a few seconds from time to time as is advised by eye doctors – this can help mitigate that tiredness of the eyes that can result from long periods of staring at a computer monitor.

Easy to add a new project – just enter its name into the box and press the New Project button and it is done.

Straight forward layout. Extremely easy to use

You can also edit the text for its windows and menus, for instance to translate into your own language.

TEXT ECHO is a text editor with special features useful for some particular tasks

Features include: wild words search and replace, options to search and replace all the files in a folder while simultaneously replacing any number of search terms in all the files, integration with the Aspell spell checker, option to make a forwarding mirror for an entire web site in one click, and it can be used as a font changing echo to edit text in other windows e.g. as a basic accessibility text magnifier and colour changer, or to edit fields in windows that are too small to see in their entirety.
