One Control Minimal Series MIDI Dual Stereo Loop (MDSL)


One Control brings players easy MIDI Loop functionality with the new Minimal Series MIDI Dual Stereo Loop pedal (MDSL). This is a stereo effects loop that is powerful for small pedalboard or large effects systems. Switch your loop easily with MIDI with either stereo or mono loops, and you can covert mono signals to stereo (dual mono operation) and send them to stereo effects. And instead of relying on a footswitch you can control the MDSL easily with MIDI from a wide variety of devices.


The OC MDSL can use between 1-8 MIDI channels to receive control signals, and the On/Off of the two effects loops via MIDI PC# or CC#. Use either PC or CC mode to control your loops easily. The input, output, and effects loop send and return jacks are all TRS stereo plugs and can be used as a full stereo loop. If the mono output signal becomes stereo via an effect connected to the effects loop, it can be output as a stereo signal to the output. Of course, you can simply use TS mono cables to have a mono loop switcher controlled via MIDI.


With the Minimal Series small size, you can use multiple MDSL units installed in remote locations, such as pedalboards and rack systems, with easy control of your loops. And beyond simple ON/OFF operation with MIDI switching, you can use the MDSL as an additional effects loop with larger switching systems like the One Control Caiman Tail Loop or the OC10+ Croc Eye. The OC MDSL is a simple and small switcher that can be used in a variety of ways to make your tone dreams come true.


MIDI Signal Characteristics:

PC# 80: Set it to PC mode. (Factory)
PC# 81: Set it to CC mode.
PC# 90: When you connect the power to the main unit, the ON/OFF setting of each loop is reset. (Factory)
PC# 91: When the power is connected to the main unit, the ON/OFF setting of each loop is set at the end.
PC# 10: Bypass Loop 1. This signal is ignored in CC mode.
PC# 11: Turn on Loop 1. This signal is ignored in CC mode.
PC# 20: Bypass Loop 2. This signal is ignored in CC mode.
PC# 21: Turn on Loop 2. This signal is ignored in CC mode.
PC# 30: Bypass both loops. This signal is ignored in CC mode.
PC# 31: Turn on both loops. This signal is ignored in CC mode.

CC# 102 / Value 10: Bypass loop 1. In PC mode, this signal is ignored.
CC# 102 / Value 11: Turn on loop 1. In PC mode, this signal is ignored.
CC# 102 / Value 20: Bypass loop 2. In PC mode, this signal is ignored.
CC# 102 / Value 21: Turn on Loop 2. In PC mode, this signal is ignored.
CC# 102 / Value 30: Bypass both loops. In PC mode, this signal is ignored.
CC# 102 / Value 31: Turn on both loops. In PC mode, this signal is ignored.


L1/L2 switch

L1 and L2 switches choose whether to change mono to stereo signals in loop 1 and loop 2 respectively.

When stereo signals are input and when mono signals are left mono, these switches are set on the top side.

If you want to convert a mono signal to stereo, set this switch to the bottom.


For example, if you enter a mono signal in the input, loop 1 is a mono effect, and loop 2 is a stereo effect, set only the L2 switch to the M>S side.

Enter a mono signal in the input, and if Loop 1 and Loop 2 are stereo effects, set only the L1 switch to the M>S side.

However, if the effect connected to loop 1 is mono input or stereo output, both switches remain on the upper side.

Also, if one of these switches is on the M>S side, the output will also be a stereo signal.


We do not make both switches M>S side. The M>S switch is used when loop 1, the signal from the input is mono, and the loop 1SEND is stereo.

For loop 2, it is used when loop 1 RETURN is a mono signal and loop 2SEND is stereo.

Otherwise, set it on the upper side.


Control:

MIDI CH: Set the MIDI channel to respond. It is used in combination with the position of the three DIP switches. Firmly fold the switch to the left or right and stop it in the middle and do not use it.


L1/L2 switches: Switch whether mono/stereo conversion is performed on loop 1 or loop 2.
Bottom position: Mono input → Stereo send, return, output
Top position: Stereo input → Stereo send, return, output
Mono input → mono send, return, output
Stereo input → mono send, return, output

Beautiful and trendy especially with minor adjustments!
Color: Red, Color: Red
The satin fabric of the bag is of great quality. Thick and resistant to snags. I partied all night with it and it held up beautifully. The color saturation of the red was perfect and against my dark dress was a perfect pop of dramatic color contrast. Notes: The magnetic closure is strong but doesn't form a complete closure because there are only two magnets. Don't turn the bag upside down or small items can fall out. There was a strong chemically smell that dissipated after a week of airing out and adding a few drops of perfume to a tissue that I kept inside the bag. I wanted a "dumpling" clutch so I altered it slightly. First I colored over the gold closure with nail polish to match the fabric color. There is something about the gold tone that detracted from the elegance. Then I added a stitch to the bottom and top corners to round the shape a bit. See pics I can hardly sew on buttons so if I could do it, anyone can! The fabric is well lined and has just enough structure to it to hold the dumpling effect without becoming too slouchy looking. The chain is nice with more elegant looking clasps than other similarly priced bags, but I didn’t use it because I wanted a clutch. Under my arm or in my hand as a clutch this was light and comfortable. Got lots of compliments and questions about where I got it. Overall a fantastic buy.

Roomy, Quality and Versatile
Color: Navy
Very nice quality and appearance. Large enough for wallet, phone, etc. Easily converted from clutch to shoulder purse with removable chain. Handle trim and chain are gold color. Wish it silver but very pleased overall and feel it is a good value.

Beautiful clutch... but chain is defective
Color: Navy, Color: Navy
This is a really beautiful clutch and the size inside is perfect for your necessities. (lip balm, hand sanitizer, pocket tissues, husbands inhaler, hand cream) I really loved that about it however, the chain which is the only option to not holding it all night is terrible. I bought this clutch for a gala but the chain got stuck on my dress just the first time I tried it on. I wish there was another option so I don't have to hold it all night. The chain is really bad quality. It will shred my lace dress. Also the chain is super long. Like too long to actually wear on on side. Or it would fall off all the time. I am 5'9 and this chain to super long for me. You would have to wear it as a cross body- and that does not look nice with formal attire. Returning.

Quality for lower price than brand sunnies
Color: Beige Tortoise Frame / Brown Gradient Lens
High quality for a low price. I'm someone who always loses my sunglasses so I won't allow myself to purchase any name brands. I've had my fair share of cheap sunnies for this reason. These are probably the best "off-brand" I've tried - and I've tried a lot. They are definitely polarized and are lightweight with a good fit - some of the cheaper brands are really tight on the ears and the plastic is clearly cheaply made, making them heavier. They are also a cute style with a variety of colors available. The other thing with cheaper sunglasses is they are usually not that great to peer out of. Some of them I can't wear to drive bc they are too dark, or not dark enough for glares on the road. These are great for driving - the lens coloring is just right to see well and also feel like you're not squinting. I'm buying another pair for when I inevitably lose these!
