[LAU] Re: Calf Vintage Delay substitute?

Thanks everyone for the many suggestions and pointers - I will summarize answers following this latest message citing the original messages. At the end I'm also listing some possible substitutes I tried...

Also in the 'generic' interface (as provided e.g. by Ardour or Carla) the dealy time is normalised 0 to 1 - so yes one can calculate the proportion (e.g. 600 ms would be 1.5) but that's the exact kind of overhead which often kills any creative mood :-) - ACE delay: Very straightforward controls which I like. Unfortunately this is mono only and seems to only work with Ardour. It also interestingly has delay time only as milliseconds albeit offering BPM sync and musical times division control - GxDelay-Stereo: has independent left/right time / gain controls (time in milliseconds) and a ping-pong control. It doesn't seem to have feedback which seems a little odd - GxEcho-Stereo: this seems to be the same as above with a fixed feedback (i.e. no feedback control) - Gxdigital_delay_st: seems to have simlar controls and approach to the Calf one: BPM tempo, possibility of sync, musical divisions, a few different modes including "tape" and hi-pass and low-pass. The problem is that although it does come up as stereo (2 ins 2 outs) it seems to actually work in mono (tested with Ardour and Carla)
