I was merely asking a question. Also, Hiby works well for me on the M6, though a little on the heavier side when it comes to resources needed.The M6 has such a small amount of RAM, 768k that is lucky it even can produce a noise. I've no idea what pulsar does, but thanks to @greenflash for opening it up in times gone by.
Of course there are 'bigger' apps like the Hiby but the M6 struggles with them if I remember correctly. If you're aware of an app that will run a higher rate without struggling let us know, cos a lot will like it.
