Suited to all types of music production, Ambience Enhancer Lite from NovoNotes fits your sound to a particular setting or mood.

Ambience Enhancer Lite analyzes incoming audio signals and breaks them down into ambience and direct sound. By adjusting only the isolated elements, Ambience Enhancer Lite keeps the direct sound untouched and adds no reverb or artificial sounds to your mix. Whether you’re editing instruments in your next single or sound effects in your movie, this plugin can make recordings sound like they were recorded in a stadium or open field to fit your music or video style.

The interface is sleek, modern and easy to use, with three knobs to control ambience: Ambience Gain (dB), Ambience Low Pass (Hz) and Ambience Delay (ms). Sound levels are represented by the circular waves to the right.

MIDI Tape Recorder is a free Mac, iPhone and iPad plugin that takes a different approach towards MIDI recording

Image Credit: Uwyn

Uwyn’s new MIDI Tape Recorder records and plays back performances with the same accuracy and precision as audio recordings.

“Most modern DAWs, even at their highest resolution, still change the timing of MIDI messages to accommodate for their editing features. These changes impact the playback of your performance as MIDI messages get reordered and delayed, causing changes in how they influence sound, sometimes in very significant ways.” MIDI Tape Recorder, a free Audio Unit v3 plugin, takes a different approach to MIDI recording.

Like an audio recorder, MIDI Tape Recorder records performances exactly as you play them, accurately reproducing every nuance of your performance. The plugin ditches the note editing, quantization and individual CC tweaking of other MIDI recorders, to give you only the features you need, allowing the plugin to capture and playback expressive and dense MIDI streams, with MPE controllers and MPE MIDI plugins.

By stripping down the plugin to its essential features, MIDI Tape Recorder is also easy to use. With simple and intuitive controls, similar to a traditional four-track audio recorder, the app is fun to record, playback and loop MIDI performances. Here’s the full feature list from Uwyn.

  • Four independent tracks for recording MIDI channel voice messages
  • Sample accurate MIDI recording and playback
  • Real-time display of active recorded notes and other received messages
  • MPE support
  • Multi-level undo and redo
  • Overdub recording
  • Punch in and punch out recording for automated regional overdubbing
  • Automated storage and recall of all recordings inside the AUv3 host project
  • MIDI file import and export for the project or each individual track
  • Repeated playback with start and stop locators
  • AUv3 parameters for all controls
  • Snap to beat option for positioning playhead and start/stop locators
  • Detection of MPE configuration message (MCM) reception for each track
  • Envoy of MCM at start of play or when pressing the track’s MPE button
  • Host transport and host tempo sync
  • Clear all recordings or clear a single track
  • Crop session to new duration
  • Fully resizable UI
  • Activity indicators for MIDI input and output on each track
  • Optional tool tips for every operation
  • Optional per-track record enable, input monitoring, and mute
  • Four virtual MIDI cable inputs if the AUv3 host supports it
  • Support for AUv3 user presets if the host supports it
  • Optional routing of first virtual MIDI cable to all tracks
  • Fully open-sourced under Creative Commons Attribution 4.0 International, an approved Free Culture License

MIDI Tape Recorder requires an AUv3 host to function. The App Store notes that the plugin currently works in Logic Pro X on some computers, but updates are on the way. MIDI Tape Recorder is free and open-source. Find the source code on GitHub here. Help fund future updates by donating to the developer here. Full documentation and FAQs can be found on Uwyn.

TesslaSE mkII is a free analog-style saturation effect

TesslaSE mkII from Variety Of Sound brings subtle saturation and widening effects from the analog into the digital domain.

Based on the plugin from 2008, the TesslaSE mkII provides “analog goodness in subtle doses”. The 2021 remake sticks to the original by slightly colouring and polishing sounds to create depth and dimension in the stereo field, rather than changing it. Its intended use is to be used here and there where the mix demands it, not as in a single instance on a bus or master.

TesslaSE mkII introduces the warmth and organic feel of analog to your digital music for an overall consistent and vibrant mix. With the mkII, “the internal gainstaging has been reworked so that everything appears gain compensated to the outside”. The transformer/tube circuit modeling got some updates too, to appear more detailed and vibrant. All non-linear algorithms got oversampled for additional aliasing suppression.

Packed into a slick, modernized user interface, the effect is easy to operate and has a low CPU profile, meaning almost zero latency is used. Use the transformer option to obtain a fancy low-end. Further increase the stereo dimension with the DIM knob. The AIR dial controls HF harshness.

TesslaSE mkII is available in VST2 format for 32 and 64-bit Windows computers only. Find the free 12MB ZIP here, complete with an included manual with more information.

Check out BPB Dirty Spring Reverb – a fantastic free spring reverb plugin with a twist

Image Credit: Bedroom Producers Blog

Bedroom Producers Blog has released another free VST plugin, BPB Dirty Spring, for a spot-on reggae guitar sound and beyond.

All hail Bedroom Producers Blog, who have spoilt us again with another free VST plugin – this time an amazing spring reverb effect. BPB is offering the plugin as a free gift – it’s available in VST2, VST3, AU and AAX formats.

Spring reverbs are often found in guitar amplifiers. In the original hardware a coiled spring between a pickup and transducer vibrates, bouncing echoes around the unit.

The Dirty Spring Decay and Tone knobs can be adjusted until the perfect character is found. You can get echo and delay effects by using the Pre knob to change the pre-delay time, adding an instantly recognisable reggae guitar rhythm.

The BPB Dirty Spring free plugin has a bitcrusher built in – hence the “dirty” – completely changing the sound to give it an echoing crunchiness. Play around with the setting and you can go from just a touch of lo-fi crackle to an 8-bit sampler effect. We’ll let BPB demonstrate:

The plugin is a follow up to Bedroom Producers Blog’s Dirty Filter and Saturator, which are both free to download.

Thanks, BPB! Head here to download your free plugin today.

Based on the Klon Centaur, The Klone is a free overdrive pedal plugin that adds character to guitars, synths, drum machines and vocals

Image Credit: Fazertone

Based on the legendary 1994 pedal, The Klone uses machine learning and circuit analysis to replicate the complex warm sound of the original.

The Klone from Fazertone aims to accurately reproduce all the unique character and tones of complex, non-linear analog distortion. The pedal is based on the Klon Centaur from Bill Finnegan, famous for its unique “transparent” overdrive that turns into crunchy but crisp distortion when turned up.

The Klone has a similarly basic layout with GAIN, TREBLE and OUTPUT knobs, and is powered by a custom neural network inference engine, optimised to work in real time without consuming excessive CPU power. While the plugin is the perfect addition to any guitar tone stack, it’s suitable for other instruments too, such as synths, drum machines and vocals.

The DRIVE/DISTORTION dial is the primary control for the plugin, adding warm, rich and sweet tones to your music.
