Here's my idea.

I have an MRL for 15 IPS, but I really want to record at 30 IPS for a project coming up.

If I align my machine (Otari MTR90mkII) with the 15 IPS MRL, then record tones on a new reel, but record all the tones at 1/2 value, they'll be the tones I need when I switch the machine to 30 IPS.

For example. The common 1K tone. Once the machine is aligned at 15 IPS, and I record a 500Hz tone, it would (I think) play back as a 1K tone at 30 IPS, because I've just doubled the speed of the tape and therefore speeding the 500Hz tone up to 1K.

So, could I do this for my 1K, 10K and 100hz tones to create my own 30 IPS MRL?
Or am I wayyy off?

EDIT: My plan was to use Pro Tools as a tone generator (I have 24 outs) to create the 30 IPS MRL, anyone see that as being an issue?
