I’m not going to go through and count but there’s something like 86 single cycle waveform samples in that toolbox folder which they’re likely including in their number.
I’ve never focused too much on how many factory samples there are so I can’t really say for sure but I think that there are more than 42 which is the number of samples there would be remaining in your estimation of 128 without counting the single cycles.
If you don’t have enough factory content there’s a bunch of free high quality samples that you can download in the link below. It’s just a random site that I found as a result of a youtube video and shared here a while back and having downloaded some myself I can say it’s legit and I was not charged. Just look for the packs marked down to free, I think that the selection rotates as to what is free and what is pay content.
If you still feel that you’re missing factory samples and you want those you’ll need to contact elektron, we’re just users, we don’t work for elektron. Some things people can help you with, others they cannot. This is one of them.
I’d look through all the folders on the +Drive and make sure though because 86 single cycle waveforms is a lot to miss if you’re exploring. You may not consider those samples but if you learn how to use them I guarantee that you will start to consider them useful.
