I can still use my RME DSP Hammerfall using an Expresscard to PCcard adapter (and I think there are Thunderbolt to Expresscard adapters? In case one upgrades to a laptop without Expresscard slot?). The upgrade roads that are not really open as far as I can see are going via USB (USB-to-Expresscard adapters exist but occupy only the USB rather than the PCIx lane of the Expresscard interface). -- David Kastrup

Paul, interesting path, and I have two questions. 1 Why did you choose Motu usb over Fireface usb class compliant ? It may of course be just a matter of cost. 2 Did you experienced any issues with the Motu AVB as reported here ? : https://linuxmusicians.com/viewtopic.php?f=6&t=18046 (don't read the whole thread, just the last pages) This said, on my side, I reused a RME DIGI96/8 PAD as reported here : https://linuxmusicians.com/viewtopic.php?f=6&t=18210 Cheers Bernard Le 14/12/2018 à 14:04, Paul Davis a écrit :

Because of the identical size factor, the difference is lost on many). That one has 8 analog inputs and 8 analog outputs. Its performance is impeccable and a T61p can make use of it. But the analog inputs are (jumper configurable) -10dB, +4dB or (I think) +14dB level, so you definitely need microphone preamps. Linux support is very good. Other input output options: S/PDIF (coax or optical), ADAT (8 channels at 48kHz or 4 channels at 96kHz), word clock, MIDI in/out. I did use this with a Mackie Onyx 1220 mixer (for sale) and the DB25 recording outputs (cable with suitable connectors also for sale). The size of this recording park is definitely overkill. It makes sense when you need highest quality digital recording _and_ online analog mix/monitoring. For only recording there are definitely more compact solutions. I actually used it recently since I was recording in the yard, did not want to crank out my not-so-mobile Mackie 1620 with Firewire card, and the Mackie Onyx Satellite I used produced xruns about once a minute (no idea what got into it and whether this is gone in current kernels). So I just used its preamps and finally did the recording with the Hammerfall DSP instead. The Hammerfall DSP itself is rather compact. You can even use it in an Expresscard slot using an Expresscard-to-Pccard (not! PCMCIA) adapter (for sale). But this won't work stacked with a USB-to-Expresscard adapter since those serve the USB lane of the Expresscard bus rather than the PCIx lane. 4 ins and 4 outs could be done in slightly lower quality using an Alesio iO|14 (for sale) which plugs into the 4-pin Firewire port on the front left (stupid place) of the T61p. However, this requires blacklisting the DICE ALSA Firewire driver and going via Ffado/Jackd instead or you'll get regular dropouts. In other words: there are reasonable options short of using ADAT (which is the main thing a Digiface is good for). -- David Kastrup
