Further to the TMS project I'm looking for a cheap or free waveform editor.
I want to use a PC soundcard to play a suitable .wav file through an amp into
the coil.

The .wav is a series of pseudorandom pulses of millisecond duration at around
150Hz. I need an editor to create the file.

Any ideas?

Something like Matlab would be the choice here.

Since I don't own it and don't want to pay for the vast array of features I will
never use, does anyone have any other ideas? What I want seems simple - a
Windows GUI where I can draw a waveform and have the soundcard play it. It must
exist somewhere.

Any PC based audio signal generator s/w on the market that is free (or cheap)?

You can convert csv values easily to a sound file using sound editing
programs such as Cool Edit Pro. Just write a program in your favorite
language to spit out such a file and Robert's your uncle.

Take a look at Goldwave : Fully functional shareware with a bunch of
options.
which might or might not handle your need for a pulse sequence.

If I were doing this, I'd use Excel to generate the time points and then
fidget
the saved (text format) file into a .wav file after I'd understood the .wav
format. But I use Excel for lots of computations where others would use a
math package.

My favorite way to create .wav files is to use LTSpice. You use the
program to create a circuit that makes the waveform you want and then save the
voltage as a .wav file. You could use piece-wise signal sources to generate any
arbitrary waveform. Or if you have the math skills, you can use a signal source
that interprets a formula. If the generated waveform is random, you can run it
through all sorts of filters to bandlimit it.

You could even simulate a Moog synthesizer with it. I've used it to
generate ultrasound doppler bloodflow signals.

LTSpice is so nice that if it could cook, I'd marry it!

Goldwave will probably do it but I have not tried. I got a copy of
that for free with a sound chip development kit.
