Recently, a number of software packages have appeared aimed at helping the inexperienced programmer produce professional graphic effects without machine code. Now, MFM offer the same style of package, but for sound.

There are 50 basic sounds with which to work. If this doesn't sound like many, bear in mind that by varying the delay built into each sound, the whole effect is changed. There are 40 different delays, together with a high and low pitch range.

It's difficult to imagine any sound that can't be synthesised with this; from horses' hooves to a penny whistle, from laser zaps to an old jalopy, though the excellence of the effect can only be appreciated with a little amplification!

You can isolate the sounds, saving the code to tape for your own use, and also create your own. The sounds can be called direct from the keyboard, their wave form drawn on the screen, then their delay varied.

The whole thing comes with a detailed manual, which also describes how to transfer to Microdrive. Well done MFM, a useful and versatile utility.
