Roland Wireless MIDI WM-1//Review and Demo 

Try the cme widi devices if you get chance. With the frequent offers you can pick up a pair for 60 quid or so and they’re great. And five will connect in a group or with other Bluetooth midi devices (e.g. korg nanokey studio) and work with low latency or low jitter. Can’t recommend enough.

Looks like normal mode suffers more from jitter. Consistent latency can be compensated for in your playing, but jitter (i.e., always changing latency) is much more difficult to work with. Great demo!

Thank you VERY much for doing such an accurate latency and timing test. I believe normal mode is using BLE, but fast mode is using a proprietary wireless protocol. I would love to see this exact same test for the CME Widi and other BLE devices because I strongly suspect that the jitter and latency issues seen here are a limitation of the Bluetooth/BLE protocol itself, rather than a problem with the Roland WM-1 product.

For playing live, I can generally detect anything more than 10ms latency. So, 40ms would be a problem, for piano/pluck sounds.

I've only just considered using wireless MIDI. Would this work if I had several different devices connected with wires, using midi thru? I'd like to have a 'master' device in my setup and just 1 wireless midi 'thingy' connected to my PC. I'm thinking about connecting all the other devices using a midi-thru 'chain'. Would this work?

The WM-1 dongle looks much longer than than the CME WIDI, which also looks neater than the Roland option. However, many thanks for demoing these as it's always good for synth heads to have a choice. Ta Starsky.

Does the battery from the WM-1 power a midi controller like plugging in via USB does?

I like wireless midi, the latency is consistent enough that it can be offset without problems. The thing that drives me crazy is Apples weird implementation. There's no way to automatically reconnect when a device is available, like everything else bluetooth. They make you click through every time you have to power down either your machine or your synth.

So, cables win, and they look cool in y opinion, I love the spaghetti monster in my setup, it makes me feel like it is an organic living thing.

I remember that Kenton made a wireless midi for play on big stage I don't know if today they sale that

How about using this live?

Do you know if I can use this on my Roland Edirol V-8? Could I just control it wirelessly from a Windows tablet or Mac what ever? Bluetooth Only ?

What are the benefits of using the Normal (higher latency) mode? Does it have greater range? Does it increase battery life? Is the connection more stable? It’s performance is obviously inferior, so I’m wondering what it’s offered at all?
