Thanks VanillaSUN. That video was awesome. Most of it I already new, but I also learned a few things. Cleared some thoughts up as well.
How good is Cuckoo? What a guy. Happy to share his knowledge, and knows the best way to share it. Very talented musician as well.
So after the video, various discussions and hints I have ascertained that there is a clear advantage to purchasing a Sound Pack if it contains " patches" like the Synthetics Pack.
But this seems to be the only pack like this. And it was the first pack I purchased, and I had thought all packs were structured this way. I was wrong. And this is what lead to my confusion and misunderstandings in this thread.
After purchasing a few more packs it seems like that is the ‘only’ pack that contains patches. The other two I just now purchased, and from what I can see all the other packs for the Rytm, only have samples, not patches. So on the whole, Avantronica is correct in saying there is no clear advantage. You only end up with samples. So you might as well make your own patches.
I have discovered that we can save a sample into the Sounds Bank which can be used over various projects, (as was explained in the video provided by VaninnaSun, 23min & 1h9min). The sample is saved in with the sound patch in the Bank, and the sample within the Bank is saved as a new sample in a new sample slot when recalled.
As Avantronica pointed out you could just use the factory sounds in the Sound Bank (correction, this is not true, I made an assumption) and use synthesis to create most of these sounds. This would be the best way as because they are not bringing in a new sample and taking up a sample spot every time you load a new sound. You can also use his suggestion of getting a simple wave sample (sine, square, triangle) and create hundreds of sound patches from these simple waveform’s. But doing it this way you will soon run into that number 127 per Pattern. (Correction, it appears that the Rytm recognises when the same sample is used for a patch so as long as you do not use 128 samples or more per Pattern you should be fine. Thanks avantronica.)
It all depends on your workflow. It seems that the possibilities for sounds design are large and there is plenty of storage. As long as you are happy to work within the constraints of the Pattern.
I learnt a lot, and have a much clearer grasp of the operating system of the Rytm.
I also learnt that my confusion about Sounds Packs was born of the first pack I happen to purchase. My first purchase was the Synthetics pack which contains “patches”. These load straight into the Bank. Synthetics pack seems like the only one designed this way. Where as the 808 and Run the Track packs I just purchased only contain sample wave files, not the patches. So they end up on the +Drive.
