Zoom Q&A with Roger Linn (monthly)

Just a heads-up: Roger Linn announced an open Zoom meeting for Q&A. Further information here: https://www.kvraudio.com/forum/viewtopic.php?f=263&t=577761

I guess this meeting will be helpful for those who are thinking of buying a Linnstrument or share their ideas on playing/setting up the Linnstrument.


Thanks for posting here :wink:

I saw the announcement and forgot to spread the word here; unfortunately I can’t make it that day/hour… (rehearsals)

Since the first Zoom meeting, Roger has decided to make them monthly on the first Tuesdays of every month at 10 AM PST.

There will be one happening soon in about 8 hours. Each meeting is recorded and can be viewed in the link below, along with a few recent previous recordings. The Zoom meeting link is also provided.

Unfortunately Roger forgot to record the July 4th Zoom meeting, so hopefully the next one will be remembered for others to view later.

The next Zoom meeting is coming up tomorrow in about 17 hours. You can join it using this Zoom link.

If the Zoom meeting is recorded this time, I will provide a brief digest of topics discussed within it, so others do not necessarily have to listen to the entire meeting.

EDIT: lets keep this all in one topic.

Sure, but I originally separated my post into a different thread because I encountered a Discourse limitation of three sequential posts by the same user (me) on a thread that I did not originally started. By starting my own separate thread, that limitation does not exist, as the LinnStrumentalists’ Log thread has proven.

So by moving and combining my thread with this one, I have to rely on someone posting after me after three sequential posts or earlier. If that does not happen I must create a new thread to continue these monthly Zoom meeting summaries, as I did just before you moved them.

Ive upped the limit to 50 …
if you post with no one replying on this topic for 4 years…(*)
I’ll reply to say congratulations, and give you another 4 years :laughing:

more seriously… do the videos get uploaded somewhere?
I could not find on Roger’s YT channel, or on the linnstrument website.
Id have thought these timestamps would be much more useful to others, if they were attached to the video recording - as you can do with YouTube.

  • 45:00 - Roger talks about Randy Jones and their perspective of the Soundplane.

is not much use to those of us not present, without actually being able to hear the discussion.

edit: ok, I found the last two here :

perhaps suggest to Roger that he copies them to YouTube, then you can add the timestamps into the description… that would make a whole lot more ‘user friendly’.

(*) that said, Id hope in that time frame, someone who reads it would come and thank you for your dedication :slight_smile:


I do not use YouTube, so that would not work. Besides, there is quite a significant difference between summaries and subtitle transcriptions - I definitely have no time for the latter. Timestamps are usually placed in the video description or a pinned comment.

I still think Roger would benefit from uploading them to YouTube for archival purposes, so I will email them about that later.

Roger will be away for the September monthly Zoom meeting, so @TigerBalm will be hosting on their behalf instead. It will start this Tuesday, September 5th, at 10 AM PST using the below Zoom link.

The September 5th Zoom call is now over and has been recorded. Instead of doing topic summaries in this thread, I think it would be a better idea to help support a PeerTube platform/instance for Poly Expression (and others) while also archiving the monthly Zoom calls on it instead.
