From Source Audio:The C4 Synth from Source Audio unites all the sound construction tools of a classic Eurorack modular synthesizer and packages them in a compact and easy-to-use effects pedal for guitar or bass. It is essentially a modular synth in a box with unprecedented tracking abilities, lightning-fast response, and vast universe of easy-to-access sound options.
The C4 offers multiple methods of preset storage and recall. For a straightforward plug-and-play experience, simply select one of the pedal's three onboard presets with the center toggle switch. The addition of a third-party MIDI controller with USB host provides access to any of the C4 Synth's 128 Factory presets. Connect the C4 to the Neuro Desktop Editor (a free download for Mac and Windows) or the Neuro Mobile App (iOS and Android) and unlock the pedal's true power. The Neuro software features a Eurorack inspired editing interface with 4 parallel voices, 3 oscillator wave shapes, 11 envelope followers, 24 modulating filters, distortion, tremolo, pitch shifting, intelligent harmonization, programmable sequencing, and more. Use the editor to create anything from classic synth tones to the sounds you've imagined, but never actually heard. Finally, for a world of great tones without all the tweaking, download sounds from the ever-expanding collection of published presets created by the C4 Neuro Community.
Once you've found your sound, burn it directly to the pedal in any of the C4 Synth's 128 preset positions, save it to your own personal effects library, or share it with the rest of the C4 Neuro Community. Never before has a guitar synth pedal offered so much is such a small package.
- Unprecedented Sound Sculpting Options: The powerful Neuro Desktop Editor (Free download for Mac and Windows) and Neuro Mobile App (iOS and Android) offer maximum sound exploration possibilities. Use Neuro's modular synthesizer inspired editor to create custom C4 Synth presets that can be burned directly to the pedal, saved to a private cloud based library or shared publically with other members of the Neuro Community.
- 128 MIDI Accessible Factory Presets Ð The addition of a third party MIDI controller with USB host provides access to any of the pedal's 128 Factory presets.
- Growing Published Presets Library: For quick access to a world of great tones without all the tweaking, try sampling sounds from the ever-expanding collection of published presets created by Source Audio and the rest of the C4 Neuro Community.
Three Position Toggle Switch: For a simple plug-and-play experience select from any of the C4's three pre- loaded, toggle switch accessible synthesizer tones.
Four Independent Voices: Mix together any of the C4's four independent Voices. Assign any of the Voices to an oscillator wave shape, monophonic or polyphonic pitch shifter, intelligent harmonizer, sequencers, or dry signal to distortion, tremolo, and filter effects.
Three Types of Oscillators: Mix and match any of the C4's three oscillator wave shapes for pure synthesizer tones. Choose from sine, square, and saw shaped oscillators.
Eleven Envelope Followers: Select from a comprehensive collection of envelope followers with adjustable attack/decay as well as ADSR triggering envelopes.
25 Filter Effects: Choose from a huge collection of filters, controllable with an envelope follower or independently modulating LFOs.
14 Different LFO Wave Shapes: Use LFO (Low Frequency Oscillators) to control the modulation of filter, vibrato, or tremolo effects. Choose from eight different LFO wave shapes, including sine, square, sample and hold, saw tooth, and more.
Two Programmable 16-Step Sequencers: Run two simultaneous sequencer patterns. Choose from several preprogrammed sequencer patterns or create custom patterns.
Two Modes of Operation: Use the pedal in Standard Mode for a classic stompbox experience or turn on Preset Mode and save a user preset (including all the on-board knob positions) to each of the three toggle switch positions.
Stereo Inputs and Outputs: Use the Neuro Editor's panning controls to route each Voice to any location in a full stereo spread.
Compact Design: The durable, anodized aluminum housing has a small footprint and sturdy hardware.

Excellent quality with just the right amount and type of connection points I needed!
Extremely good quality. I've used many Anker product over the years and this one didn't disappoint! Needed it to run a laptop on my network in isolation mode and to have accessible connections for ethernet as well as a wireless mouse and extra cooling fan as my laptop has only 1 standard size USB 3.0 port. This is the mini version so It won't necessarily supply enough juice to charge your laptop at the same time (there's another 8 in 1 made by Anker for that) but it can supply enough power to maybe get you through a very trying session, very short term. Super-easy to connect and just works. Fits comfortably in my carry bag too. Very light weight, good heat dissipation although I didn't really have any or at least not much. Compatible with all the connectors you see in the picture. In my case at least, it wasn't a luxury it was a necessity and it proved it's value immediately.

USB ports charge.
Relatively cheap, lightweight, and better than most. It gets warm, but not hot. The Video adapter was immediately recognized by my Macbook and works flawlessly at all resolutions made available (much higher than Windows PCs) I used it both as the recipient of my 65W Mac charger, and the Mac received its power from this device; I also had the 65W Mac charger plugged directly into the Mac, and this plugged into the second USB-C plug on the mac. It works (HDMI monitor) both ways. It says that the ports are not for "charging", however be aware that they do charge when devices are connected, for example my iPhone to the extra USB-C port, or the USB-A port. My Logi back-lighted keyboard lights up too. I don't know why they say it is not for charging. Perhaps it is simply saying there are no ports expressly intended to do charging without connecting to your computer.

High quality and all the right connection types
This works great. I've used it for both my MAC and PC. I really love the Ethernet on the end and the HDMI connections (which modern laptops don't include at times). This is a great adaptor and highly recommend.

One complaint
Works very well and solved port issues on my X1 Carbon. My only quibble is that the C interface cable from the unit to the PC is a bit too stiff and tends to lose connection if things move about.

Perfect for my use
Works as intended. Solid build quality and works with my Windows laptop through the USB C connection. I wish the product description would clarify that the USB ports do not support video.
